16x - 4y = 12

4x - y = 3

4x = 3+y

x= 3+y/4

for y = 1

x= 3+1/4 = 1

y = 2

x=3+2/4 = 5/4 = 1.25

y = 3

x = 3+3/4 = 6/4 = 1.5

The vertex of the equation y = x² + 2x -3 is (-1, -4).

The term vertex in math is known as a point on a polygon where the sides or edges of the object meet or where two rays or line segments meet.

Here we have the expression y = x² + 2x -3

As we all know that the given equation of parabola is written as,

=> y = ax² + bx + c

As we all know that the vertex of the parabola is given by (h, k).

Here we have calculated the value of the x coordinate of vertex as ,

=> h = -b/2a

And the value of y coordinate of vertex k by using the formula,

=> k  = y(h)

Through the given equation we have identified the value of a = 1, b = 2 and c = -3

Then the value of x coordinate is calculated as,

=> h = -2/(2 × 1)

Therefore, the value of h is -1

Then the value of y coordinate is calculated as,

=> k = y (-1)

Here we have to substitute -1 in the equation, then we get

=> k = (-1)2 + 2(-1) - 3

=> k = 1 - 5 = -4

Hence the coordinate of the vertex is (-1, -4).

An x-y (or bivariate) plot is any graph or plot with two axes. The "x-axis" is typically the horizontal axis, whereas the "y-axis" is typically the vertical axis.

Your plot's axes should be identified, and the scale should be chosen (if the graph is not already labeled). Plot the first two pairs of numbers first (the top row of numbers).

Finding the number a on the horizontal, or x-, axis and tracing up or down from there while maintaining a parallel path to the vertical, or y-, axis, will allow you to draw the point at (a, b) on the Cartesian plane.

The position of the point is this area (a, b). The intersection of the two axes defines the plane's center. It is referred to as the beginning or point (0,0).

Each axis is further subdivided into equal units starting at the origin: rising, positive numbers on the x-axis and up the y-axis; falling, negative numbers on the x-axis and down the y-axis.

For math equation, To eliminate a variable, it must have the same coefficient. So if the coefficients of the variables are not the same then first equate the coefficients by multiplying or dividing them.

Determine the set of solutions to the following system of equations using the elimination method, if x and y are variables in the set of real numbers.

Completion:

1. x + y = 1 and x + 5y = 5

To eliminate the y variable, remember that the coefficients of y must be the same, so the equation x + y = 1 times 5 and the equation x + 5y = 5 times 1, then:

x + y = 1     │× 5 => 5x + 5y = 5

x + 5y = 5   │× 1 => x + 5y = 5

5x + 5y = 5

x + 5y = 5

--------------- –

4x + 0 = 0

x = 0

Same as step I, there is no need to equate the coefficients to eliminate variable x because the coefficients are the same, then:

x + y = 1

x + 5y = 5

--------------- –

0 + –4y = –4

y = 1

So, the solution set is {(0, 1)}.

Five rays from common endpoints or vertex form 10 distinct angles.

Angles are constructed when two lines intersect at a point. The measurement of the 'opening' between these two rays is called an 'angle'. The symbol represents it ∠. Angles are usually measured in degrees and radians, which is a measurement of circularity or rotation.

In geometry, an angle is constructed when two rays are joined at their endpoints. These rays are named the sides or arms of the angle.

The arms and the vertex are two primary parts of an angle.

The two rays which converge at a common point to create the angle are called the arms of the angle.

Answer:

15 nickels and 8 dimes

Step-by-step explanation:

Let N = number of nickels and D = number of dimes

N - D = 7   (the number of nickels exceeds the number of dimes by 7.)

or

N = D + 7

Total value of N nickels = 5N

Total value of D nickels = 10D

Combined total value => 5N + 10D = 155

Substitute for N in terms of D
==> 5(D + 7) + 10D = 155

5D + 35 + 10D = 155

15D + 35 = 155

15D = 155 - 35

15D = 120

D = 120/15

D = 8

N = D + 7 = 8 + 7 = 15

15 nickels and 8 dimes

The measure of angle B is 50 degrees and angle C is 80 degrees.

The angle sum property of a triangle states that the sum of interior angles of a triangle is 180°.

In the given triangle, we can use the concept of triangle angle sum to find the unknown measures.

We know that the sum of the angles in a triangle is always 180 degrees.

Therefore, if we know two angles in a triangle, we can find the third angle by subtracting the sum of those angles from 180.

We are given that angle A is 50 degrees. We are also given that angles B and C are unknown. Therefore,

we can use the following equation to find the measure of angles B and C:

A + B + C = 180

50 + B + C = 180

B + C = 180 - 50

B + C = 130

So the sum of angles B and C is 130 degrees. Therefore, we can't find individual measures of angles B and C.

Alternatively, we can use the property of the angle pair which states that if two parallel lines are intersected by a transversal, the alternate interior angles are congruent.

If we know that angle A and angle B are congruent, we can find the measure of angle B as 50 degrees. As a result, angle C will be 180 - 50 - B = 130-50 = 80 degrees.

Hence, the measure of angle B is 50 degrees and angle C is 80 degrees.

It is option D (f-¹ (x) = x-3/5

The solution of the given linear equations is (x,y) = (1,-1).

The given linear equations are

8x + 3y = 5 - - - ( 1 )

3x - 2y = 5 - - - ( 2 )

As the RHS of both equations is equal, equating the LHS of both equations, we get,

8x + 3y = 3x - 2y

⇒ 8x - 3x = - 2y - 3y

⇒ 5x = - 5y

⇒ x = - 5y ÷ 5

⇒ x = - y

By substituting x = - y in equation ( 1 ), we get,

8x + 3y = 5 - - - ( 1 )

⇒ 8 ( - y ) + 3y = 5

⇒ - 8y + 3y = 5

⇒ - 5y = 5

⇒ y = - 5 ÷ 5

Lance and Alberto cycled along the same 75 km route. Speed of Alberto is 30 km/ hr

Since, Lance takes 3 hours to complete 75km, his speed will be

v= [tex]\frac{75}{3}[/tex]

v= 25 km/hr

The amount of time taken by Lance to complete 10 km is

t= 10/25

t =0.4 hr

t= 0,4×60 min

t=24 min.

Since Alberto started 4 min late and  time taken by Alberto to complete 10 km is

t= 24-4

t=20 min.

Hence, speed of Alberto is v=10/0.33

v=30 km/hr.

A measure of how quickly something is moving is speed. The distance an object travels in a single time unit is its speed. The speed formula is: Distance times speed. Meters per second (m/s), kilometres per hour (km/h), and miles per hour (mph) are the most common units of speed.

Speed is calculated by dividing distance by time. You must be familiar with the distance and time units in order to determine the units of speed. The units will be measured in meters per second (m/s) because distance is measured in meters (m) and time is measured in seconds (s).
