Solve the problem
7x-4y=-7
5x+y=22

x=3, y=7. (3, 7).

Step-by-step explanation:

7x-4y=-7

5x+y=22

y=22-5x

7x-4(22-5x)=-7

7x-88+20x=-7

27x=-7+88

27x=81

x=81/27

x=3

7(3)-4y=-7

21-4y=-7

4y=21-(-7)

4y=21+7

4y=28

y=28/4

y=7

i believe it is c.y = 9x

rise over run. 9 units up over 1 unit right or 9/1

false

step-by-step explanation:

false.   two legs of the trapezoid would be congruent, but the other two would not.   were all the legs congruent, then we'd have a square; were the 2 shorter sides congruent and the 2 longer sides also congruent, we'd have a rectangle.
