Find the solution to this system:

Equation 1: 5x - 2y = -11

Equation 2: -2x + 5y = 17

Step 1: To create x-coefficients that are additive inverse, Equation 1 can be multiplied by

A.) 2

B.) -5

C.) 11

The answer was 2

Solution:

Given system of equations are:

Equation 1: 5x - 2y = -11

Equation 2: -2x + 5y = 17

Step 1: To create x-coefficients that are additive inverse

Equation 1 can be multiplied by ?

The additive inverse of a number "x" is the number that, when added to "x" yields zero

Multiply eqn 1 by 2

2(5x - 2y = -11 )

10x - 4y = -22 eqn 3

Multiply eqn 2 by 5

5(-2x + 5y = 17)

-10x + 10y = 85 eqn 4

Now take eqn 3 and eqn 4

10x - 4y = -22

-10x + 10y = 85

So here, 10x and -10x will give 0

Thus, to create x-coefficients that are additive inverse, Equation 1 can be multiplied by 2

so a parallelogram is just like a square base times height. multiply 40 and 39 to get 1560 inches.

a triangle is base times height divided by two. so multiply 7.9 and 5 and then divide it by 2 to get 19.75inches.

the kite can be split into two separate triangles and added together to get the total area. 30 x 4 /2 which equals 60. make sure to double it for the two triangles making 120.
