1) solve, using the substitution method.

d + e = 2
d – e = 4

a) the solution is (3, –1).

b) there are an infinite number of solutions.

c) there is no solution.

d) the solution is (5, 1).

2) solve, using the substitution method.

4x + 2y = 11

x – 2 = –2y

a) (3, -1/2)
b) (0, - 2)
c) (0, -11/2)
d) (7, -5/2)

2,600 divided by 80 = 32.5

step-by-step explanation:

dilation scale factor 2: starting with δabc, draw the dilation image of the triangle with a center at the origin and a scale factor of two. notice that every coordinate of the original triangle has been multiplied by the scale factor (x2). dilation with scale factor 2, multiply by 2.
