The equation which represents the same line as the points in the table is y = -3/4 x + 2. (Option C)
The equation of the points given in the table can be determined by using the slope-intercept form which is given by:
y = mx + b
where m is the slope of the line and b is the y-intercept.
The slope of the line can be determined by:
m = rise/run = Δy/ Δx = (y2 – y1)/(x2 – x1)
Hence, taking two points from the table say (-4, 5) and (0, 2)
m = (2 – 5)/(0 – (-4)) = -3/4
y intercept is the value of y when x = 0
From the table, y-intercept b = 2
Hence, the equation of the line is: y = -3/4 x + 2

Fawaz when hopping for a new phone ale tax where he live 9% the price of the phone i $33 find the total price including tax round to the nearet cent
The total price including tax, Fawaz has to pay is $36 round to the nearest cent.
To find the total price of the phone including tax, we need to add the tax amount to the price of the phone. The tax rate is 9%, which means that for every $1 of the price of the phone, $0.09 will be added as tax. To find the total price including tax, we can use the following formula:
Total price = Price of the phone + (Price of the phone x Tax rate)
Given the information in the problem, we know that:
Price of the phone = $33
Tax rate = 9% (expressed as a decimal)
Plugging these values into the formula, we get following equation:
Total price = $33 + ($33 x 0.09)
To solve for total price, we need to calculate ($33 x 0.09)
= $3
Total price = $33 + $3
Total price = $36
So the total price including tax, Fawaz has to pay is $36 round to the nearest cent.
In simple words, we have multiplied the price of the phone with the tax rate and then added the tax amount with the price of the phone to get the total price including tax.
Note: The tax rate is given as 9% which is equal to 0.09 in decimal form.
Therefore, The total price including tax, Fawaz has to pay is $36 round to the nearest cent.

A rectangular flag i 60 cm by 96 cm. What are the dimenion of a cale drawing of the flag uing the cale 1:6?
The dimensions of the scale drawing are 10cm x 16cm.
A scale drawing is a representation of an object or a space that is smaller or larger than the actual object or space. The scale of a drawing is represented as a ratio, such as 1:6, which means that every 1 unit on the drawing represents 6 units on the actual object or space.
In this case, we are given a rectangular flag that has dimensions of 60 cm by 96 cm, and a scale of 1:6. This means that for every 1 cm on the scale drawing, the actual flag is 6 cm. To find the dimensions of the scale drawing, we need to divide the dimensions of the actual flag by the scale.
To find the length of the scale drawing, we divide the length of the actual flag (60 cm) by the scale (6):
Length of scale drawing = 60 cm / 6 = 10 cm
To find the width of the scale drawing, we divide the width of the actual flag (96 cm) by the scale (6):
Width of scale drawing = 96 cm / 6 = 16 cm
So, the dimensions of the scale drawing are 10cm x 16cm.

Aubrey read 29 book and Eli ride 52 book what number i equal to the number of book already read
So, the number of books already read by both Aubrey and Eli is 81 books.
Aubrey read 29 books and Eli read 52 books. To find the total number of books they have read together, you need to add the number of books read by Aubrey to the number of books read by Eli. This is because the total number of books read by both of them is the sum of the number of books read by each of them individually.
In mathematical terms, if Aubrey reads x books and Eli reads y books, the total number of books read by both of them is represented as x + y.
In this case, the number of books read by Aubrey is 29 and the number of books read by Eli is 52. So, to find the total number of books read by both of them, you would add 29 + 52 = 81
Therefore, the number of books already read by both Aubrey and Eli is 81 books.

A string is cut into fourths. Three of the fourths are thrown away. One third of the remaining fourth is cut away and the piece left over is 6 feet long. How long was the string initially?
Using Algebraic expressions, the original length of the string was 72 feet.
Algebraic ExpressionsWhen addition, subtraction, multiplication, division, and other mathematical operations are performed on variables and constants, the result is a mathematical statement known as an algebraic expression.
Let's say James and Natalie were playing with matchsticks when they had the idea to create number patterns with them. James made the number 4 with four matchsticks. In order to create a pattern with two 4s, Natalie added three extra matchsticks.
They understood that they could keep adding three matchsticks each round to make an additional "four" by doing so. They deduced from this that, generally speaking, in order to create a pattern with n number of 4s, you need 4+ 3(n-1) sticks. We refer to 4+ 3(n-1) as an algebraic expression in this case.
Let x be the length of the string,
when it is cut into 4 halves,
the length becomes x/4,
then it is again cut 1/3,
Now, it is given that 1/3 × x/4 = 6

The solution for the absolute function is h < 2.
What is an absolute function?The variable in the absolute value bars makes up an essential algebraic function known as the absolute value function. The most widely used version of the absolute value function is f(x) = |x|, where a = 1 and h = k = 0. The general form of this function is f(x) = a |x - h| + k.
When we extend the absolute value function f(x) = |x|, we can write it as x if x 0 and -x if x 0 since the range of this function, f(x) = |x|, is always non-negative.
The function will be solved as,

How do you factor to find all real solutions?.
Transfer all terms to one side of the equation, usually the left, using addition or subtraction. Factorise the equation completely. Equate each factor equals zero, and then solve. Record each solution from Step 3 as a solution to the original equation.
For example, we have an equation x² + 2x = 8x – 8
Step 1. First, subtract 8x from each side.
x² + 2x – 8x = 8x – 8x – 8
x² – 6x = -8
Now, add 8 to each side.
x² – 6x + 8 = -8 + 8
x² – 6x + 8 = 0
Step 2. We identify the left as a trinomial and factor it accordingly:
(x – 2)(x – 4) = 0
Now the two factors are (x – 2) and (x – 4).
Step 3. Now we assigned each factor equal to zero.
(x – 2) = 0 and (x – 4) = 0
x = +2 and x = +4
Step 4. The last step is to join the two previously solved solutions, x = 2 and x = 4, into one solution for the original problem.
x² + 2x = 8x – 8

What is the boundary line for the linear inequality 2x 3y 6?.
A point (x1, y1) is said to satisfy the inequality ax + by ≤ c if a(x1) + b(y1) ≤ c. The graph of a linear inequality is the set of all points in the plane which satisfy the inequality.
Now, the given equation is 2x + 3y ≥ 6
We can find multiple points (x, y) that satisfy the given inequality. For now, we can take the point (1,2).
To check if (1,2) satisfies the inequality, put x = 1, y = 2 in the inequality.
2 + 6 ≥ 6
8 ≥ 6, which is true.
This line cuts the plane in half. One half contains all points (x, y) with 2x + 3y > 6 and the other half contains all points with 2x + 3y < 6.
To find which half is which, we need only check one point on one side of the line. (if the line does not cut through (0, 0), we can check that point easily.) In this case we find that 2(0) + 3(0) < 6.
Therefore the solution to the inequality 2x + 3y ≥ 6 is the half plane not containing (0, 0) shaded below. We can also represent it with arrows as in the diagram on the right.
Since the region includes the points along the line 2x + 3y = 6, we draw a
solid line. We use a dotted line when we want to indicate strict inequality as in the solution set to 2x + 3y > 6 shown in the diagram.
Thus, this is the boundary line for the given inequality.

What is a Triangle?A triangle is a plane figure or polygon with three sides and three angles.
A Triangle has three vertices and the sum of the interior angles add up to 180°
Let the Triangle be ΔABC , such that
∠A + ∠B + ∠C = 180°
The area of the triangle = ( 1/2 ) x Length x Base
For a right angle triangle
From the Pythagoras Theorem , The hypotenuse² = base² + height²
if a² + b² = c² , it is a right triangle
if a² + b² < c² , it is an obtuse triangle
if a² + b² > c² , it is an acute triangle
Given data ,
Let the triangle be represented as ΔABC
Now , the measure of side ∠A = 82°
The measure of side ∠B = 54°
The measure of side ∠C = x°
Now , for a triangle ,
∠A + ∠B + ∠C = 180°
Substituting the values in the equation , we get
82° + 54° + x° = 180°
On simplifying the equation , we get
136° + x° = 180°
Subtracting 136 on both sides of the equation , we get
x = 180° - 136°
x = 44°
Now , for a straight line , the angle in a straight line is 180°
So , x + y = 180°
Substituting the values in the equation , we get
44° + y = 180°
Subtracting 44° on both sides of the equation , we get
y = 136°
Now . the measure of z = measure of y ( alternate interior angles )
So , z = 136°

Equivalent sets must have the same cardinality, i.e., n(A) = n(B) where, n(A ) and n(B) are the number of elements in set A and set B respectively.
Equivalent Sets means that there should be a one-to-one correspondence between the elements of both sets. Equal sets and equivalent sets are two different concepts. A is equivalent to B if A and B are two sets such that n(A) = n(B). This means that two equal sets are always equal, but the opposite of the same may or may not be true.
Statement: Set A and Set B are equivalent.
Proof: Let us consider two sets A and B. Let 'a' be any member of A. We need to show that "a" is also a member of B. Then let "b" be any member of B. We must show that b is also a member of A.

20 ft-9[tex]\frac{1}{2}[/tex] in+ 2[tex]\frac{1}{2}[/tex] in = 21 ft meaning, Tim has to jump 2[tex]\frac{1}{2}[/tex] in more inches just to get to 21 ft, then...
He needs to jump an additional 2[tex]\frac{1}{4}[/tex] + [tex]\frac{1}{4}[/tex] = 2[tex]\frac{2}{4}[/tex] = 2[tex]\frac{1}{2}[/tex] in to break the record. Note: he needs to jump at least [tex]\frac{1}{4}[/tex] in farther than the record because jumps only are measured to the nearest [tex]\frac{1}{4}[/tex] inch.
Therefore Tim must jump 2[tex]\frac{1}{2}[/tex] in + 2[tex]\frac{1}{2}[/tex] in = 5 in farther to break the record.
