How do you graph an absolute value piecewise function?.

Answers

Answer 1

The process to graph an absolute value piecewise function is explained below .


Let us consider the Absolute value function as :

y = | x -2 | ;

this absolute function can be written in piecewise wise form as :

⇒ [tex]y =\begin{array}{cc} \{ & \begin{array}{cc} -x+2 & x < 2 \\ x-2 & x\geq 2 \end{array}\end{array}[/tex]  ;

this piecewise function means that the main function divides into two pieces ,

for any input value that is less than 2 , the function"-x+2" will be used , and

for any input value greater than or equal to 2, the function "x-2" , will be used ;

for example : if x = 3 , then ⇒ y = 3 - 2 = 1  ;

and is x = 1 , then ⇒ y = -1 +2 = 1 ;

the points to be plotted are (3,1) and (1,1) .

The graph of this absolute value piecewise function is shown below .

What is an exponential function?

The mathematical formula f (x) = an x denotes an exponential function. a constant known as the function's base and a variable called x are present.

Any function whose constant is raised to the power of an input is said to be exponential.

An exponential function looks like this:

[tex]$y=a b^x$[/tex]

Where:

A stands for the starting point.

B is equal to 1 plus the rate r.

The following ordered pair can be seen in the table.

(x,y) = {(0,72000) (3,90000)}

What is the solution for Y =- 3x 8?.

Answers

The y-intercept is (0, 8).

The equation, y = mx + b, is the slope-intercept form of a straight line.

Here, x and y are the coordinates of the points, m is the gradient, and b is the intercept of the y-axis.

y = mx + b is the slope-intercept form of the equation of a straight line. In the equation y = mx + b, m is the slope of the line and b is the intercept.

The value of b is equal to y when x = 0, and m shows how steep the line is. The slope of the line is also called the gradient.

The y-intercept is what you get when you plug in x = 0

Similarly, the x-intercepts are what you get when you plug in y = 0

So, because we're finding the y-intercept, plug in 0 for x and solve for y.

Therefore, the y-intercept is (0, 8).

A factory can produce two products x and y with a profit approximated by p=14x+22y-900.

Answers

The vertices of the feasible region are  (0,100) (0,700) (400,500)

The minimum profit is (0,100)  and the maximum profit is (400,500)

Given that, P=14x+22y-900  where p is the profit

y > x +100    y must exceed the production of x by at least 100 units

x+2y<1400

x>0

We cannot produce negative quantities

Substitute y = x+100 into x+2y <1400

x+2(x+100) < 1400

x+2x+200 <1400

3x+200<1400

Subtract 200 from each side

3x<1200

Divide by 3

x<400

y = x+100

y = 400+100

y = 500

(400,500)

y > x +100

when x=0  y > 100  

x+2y <1400

0+2y <1400

2y <1400

y <700

When x=0  y = 700

a)  The vertices of the feasible region are  (0,100) (0,700) (400,500)

b)  Maximum and minimum profit occur at the vertices.

P=14x+22y-900

P(0,100) = 14(0) +22(100)-900 =2200-900=1300

P(0,700) = 14(0) +22(700)-900 =15400-900=14500

P(400,500) = 14(400) +22(500)-900 =5600+11000-900=15700

Thus, The vertices of the feasible region are  (0,100) (0,700) (400,500)

Which equation represents the graph?

Answers

Answer:D y=-2x-1

Step-by-step explanation:

To solve this problem, we first need to look at the direction of the line to determine whether the slope is positive or negative. Since the left portion of the line is Quadrant 2 and the right portion in quadrant 4, the slope will be negative. Anytime the line looks like \ it will be negative, while / is positive. This immediately eliminates answers A and C. Now, our next order of business is to find the slope of the line. To do this, we need to pick two points on the line and use the equation (y2-y1)/(x2-x1). Any points on the line will work, so even if you do not use the same as me, you still should get the same answer (this is a good way to check!)

point 1: (-2,3)

point 2: (0,-1)

(-1 - 3) / (0 - -2) = (-1 - 3) / (0 + 2) = -4/2 = -2

Since the slope is -2, we know the answer is d. Hope this helps

intersection points with the x-axis means that their y-values are 0 !

that is the whole trick, as I am sure you experienced already with lines and y-intersects (x = 0) and x-intersects (y =0).

so, we need to solve for x, when y = 0 :

x² + 4x + 4 + 9 = 37

x² + 4x - 24 = 0

the solution to a quadratic equation

x = (-b ± sqrt(b² - 4ac))/(2a)

in our case

x = (-4 ± sqrt(4² - 4×1×-24))/(2×1) =

Determine three ways to have a total of 14 apples and bananas

Answers

Answer:

6 apples and 5 bananas

Step-by-step explanation:

x + y = 11

x = 11 - y

1.75x + 0.70y = 14

1.75(11 - y) + 0.7y = 14

19.25 - 1.75y + 0.7y = 14

5.25 = 1.05y

y = 5

x = 11 - 5 = 6

Answer: 4 apples and 10 bananas

Step-by-step explanation:

Consider: a=apple, b=bananas

1) a + b = 14 // 14 total of apples and bananas

   a = 14 - b

2) 1.75a + 0.70b = $14 // $14 worth of apple and bananas

3) Substituting 1) in 2):

  1.75(14 - b) + 0.70b = 14

  24.5 - 1.75b + 0.70b = 14

   b = 10.5 / 1.05

    b = 10

4) Substituting 3) in 1):

   a = 14 - 10

How many solutions does Y =- 3x 7 have?.

Answers

The equation, Y = - 3x + 7 has infinitely many solutions.

Here we are given the equation y = - 3x + 7.

Now this equation has 2 variables. when an equation has 2 variables, there must be at least 2 equations for the system to have a unique solution, hence the given equation cannot have 1 unique solution.

If we plot this equation on the graph we will see that it makes a never-ending line.

Here for every value of x, we get a different value of y, which can be easily seen in the graph.

Therefore we cannot conclude that this will have no solution. Hence since there can be infinite possible answers to the above equation, this has infinitely many solutions.

Find the coordinates of the circumcenter of AABC with vertices A (1, 0), B (8, -7), and
(7,-4).

Answers

The coordinates of the circumcentre P(x, y) of ΔABC with vertices A (1, 0), B (8, -7), and C(7,-4) is P(6.4, 1.6).

What is circumcentre?

If there is a circle that encompasses all of the vertices of a polygon, it has a circumcenter that is the centre of the circle. The circumcentre and ensuing circumcircle of a triangle are both always distinct.

Let P(x, y) be the circumcentre

Then

PA = PB = PC

⇒PA² =PB² =PC²

Now, PA² = PB²

⇒ (x−1)² +(y−0)² =(x−8)² +(y+(-7))²

⇒  x = 8 − y

And,  PB² = PC²

⇒ (x−8)² +(y+(-7))²= (x−7)² +(y−(-4))²

⇒  x = 24− 11y

Factor out x from both equations

8 − y = 24− 11y

10y = 24 - 8

10y = 16

y = 16/10

y = 1.6

For x

x = 8 − y

x = 8 − 1.6

x = 6.4

Thus, the coordinates of the circumcentre P(x, y) of ΔABC with vertices A (1, 0), B (8, -7), and C(7,-4) is P(6.4, 1.6).

3.75 pounds of the trial that contains 35% nuts.

What is an equation?

An equation is a mathematical statement that is made up of two expressions connected by an equal sign.

Example:

2x + 4 = 8 is an equation.

We have,

Trial mix A = x

= 75% nuts.

Trial mix B = y

= 35% nuts

Now,

Two equations are:

x + y = 10 _____(1)

x = 10 - y _____(2)

0.75x + 0.35y = 10 x 0.60 ______(3)

Substituting (2) in (3)

0.75 (10 - y) + 0.35y = 6

7.5 - 0.75y + 0.35y = 6

7.5 - 6 = 0.75y  - 0.35y

1.5 = 0.40y

y = 1.5/0.40

y = 3.75

Now,

x = 10 - 3.75

x = 6.25

Thus,

Given are the equations as shown in the image.

The equation that is not a polynomial identity is option B.

Therefore, Option B does not represent a polynomial identity.

Answers

The value of side x for the right-angle triangle is 8.6 cm.

What is trigonometry?

The branch of mathematics that sets up a relationship between the sides and the angles of the right-angle triangle is termed trigonometry.

The trigonometric functions, also known as a circular, angle, or goniometric functions in mathematics, are real functions that link the angle of a right-angled triangle to the ratios of its two side lengths.

Given that the sides are Hypotenuse H = 15 cm, perpendicular = x, and the base is y.

The value will be calculated as,

x = [ sin(35) x 15 ]

Answer: a. i. In this context, x represents the number of cups of water.

ii. In this context, y represents the number of cups of lemon juice.

iii. Yes, there is a proportional relationship between x and y. The recipe states that for every cup of water, there should be one cup of lemon juice. This means that as the amount of water increases, the amount of lemon juice also increases in the same proportion.

b. To plot the pairs in the table in a coordinate plane, we can use the values of x and y as the coordinates. For example, the first pair (x=1, y=4) would be plotted at the point (1, 4) on the coordinate plane. Similarly, the second pair (x=2, y=1) would be plotted at the point (2, 1), and so on.

Please note that the table provided with X, Y and ²14,1 is incorrect, it is not possible to plot these values in a coordinate plane as the values are not valid.

Consider the line y = -2-4x.
What is the slope of a line perpendicular to this line?
What is the slope of a line parallel to this line?
Slope of a perpendicular line:
Slope of a parallel line:

Answers

For the line y = -2-4x, the slope of a line parallel to this line is -4 and the slope of a line perpendicular to this line is 1/4.

What is slope?

A line's steepness and direction are measured by the line's slope. Without actually using a compass, determining the slope of lines in a coordinate plane can assist in forecasting whether the lines are parallel, perpendicular, or none at all.

The equation for the line is - y = -2 - 4x.

The slope of a line is represented by the coefficient of the x term. In this case, the slope of the line y = -2 - 4x is -4.

The slope of a line perpendicular to a given line is the negative reciprocal of the slope of the given line. The negative reciprocal of -4 is 1/4.

So, the slope of a line perpendicular to y = -2 - 4x is 1/4.

The slope of a line parallel to a given line is the same as the slope of the given line.

So the slope of a line parallel to y = -2 - 4x is -4.

Therefore, the parallel and perpendicular slope is -4 and 1/4 respectively.

Julia parcourt 1200 km par mois en voiture. Elle possède
une voiture à essence qui consomme 6 L d'essence par 100 km.
Je raisonne
Pour réduire son impact écologique et économiser,
Julia s'informe sur les voitures hybrides. Elle apprend
qu'une voiture hybride consommerait
d'essence de moins que sa voiture actuelle.
Si le prix d'un litre d'essence est de 1,30 $ pendant
toute l'année, combien Julia économiserait-elle
en essence par année si elle remplaçait sa voiture
actuelle par une voiture hybride?

Answers

Answer:

Julia parcourt 1200 km par mois en voiture, donc elle parcourt 1200 x 12 = 14400 km par an.

Sa voiture actuelle consomme 6 L d'essence par 100 km, donc elle consomme 6/100 x 14400 = 864 L d'essence par an.

Si elle remplaçait sa voiture actuelle par une voiture hybride qui consomme moins d'essence, elle économiserait 864 L d'essence par an.

Si le prix d'un litre d'essence est de 1,30 $, alors Julia économiserait 864 x 1,30 = 1129,20 $ par an si elle remplaçait sa voiture actuelle par une voiture hybride.

express the following as a ratio in it's simplest form: 48 seconds: 1 minute​

Answers

Answer:

4:5

Step-by-step explanation:

We know that 1 minute is equals to 60 seconds.

So the ratio is now:

48 seconds : 60 seconds

We need to simplify the ratio in its simplest form. 12 goes into both 48 and 60 so:

48/12 = 4 seconds

60/12 = 5 seconds

So the ratio 48 seconds: 1 minute in its simplest form is:

4 seconds : 5 seconds

Find (−7z−4)−(−3z+1) .

Answer:

[tex] \sf \: -4z - 5 [/tex]

Step-by-step explanation:

Given expression,

→ (-7z - 4) - (-3z + 1)

Let's simplify the expression,

→ (-7z - 4) - (-3z + 1)

→ -7z - 4 + 3z - 1

→ (-7z + 3z) + (-4 - 1)

→ (-4z) + (-5)

→ -4z - 5

Hence, the answer is -4z - 5.
