Each side length of the parallelogram at the right is multiplied by four. Describe the change in the perimeter.

Answers

side length1 = x
side length2 = y

2x + 2y = perimeter

2(4x) + 2(4)y = new perimeter
8x + 8y = new perimeter

new perimeter = 4 times the old perimeter

a.) Using the graph,what is the solution to this system?
b.) Solve the system algebraically to confirm your answer to part (a).

Answers

a.) By using the graph, the solution to this system is (3, 5).

b.) Solving the system algebraically gives the same answer in part (a).

How to graphically solve this system of equations?

In order to graphically determine the solution for this system of linear equations on a coordinate plane, we would make use of an online graphing calculator to plot the given system of linear equations while taking note of the point of intersection;

y=x+2 ......equation 1.

y=2x-1 ......equation 2.

Part a.

Based on the graph shown, we can logically deduce that the solution for this system is represented by the ordered pair (3, 5) in quadrant I.

Part b.

By using the substitution method to substitute for y, we would set the two equations equal to one another;

x + 2 = 2x - 1

2x - x = 1 + 2

x = 3

y = x + 2

y = 3 + 2

y = 5.
