1. x - 5y = -5 4x + 20y = 20

x = 0 , y = 1

Step-by-step explanation:

x - 5y = -5

  +5y    +5y

x = -5 + 5y

4x + 20y = 20

4(-5 + 5y) + 20y = 20

-20 + 20y + 20y = 20

-20 + 40y = 20

+20             +20

40y = 40

/40    /40

y = 1

x = -5 + 5y

x = -5 + 5(1)

x = -5 + 5

x = 0

So, using the method of substitution, we get x = 0 and y = 1.

I agree with manamoto13 , the answer is  y= 1  and x=0

false

step-by-step explanation:

two pairs of adjacent sides are of equal length. this implies that one diagonal divides the kite into congruent triangles, and so the angles between the two pairs of equal sides are equal in measure. it also implies that the diagonals are perpendicular.
