Answer:
x = 1, y = -2
Step-by-step explanation:
15x + 3y = 9 (1)
10x + 7y = -4 (2)
3 × (2) - 2 × (1)
3 × (2)
30x + 21y = -12 (3)
2 × (1)
30x + 6y = 18 (4)
(3) - (4)
15y = -30
y = -30 / 15
y = -2
sub y = -2 into (1)
15x + 3y = 9
15x + (3 × -2) = 9
15x - 6 = 9
15x = 9 + 6
15x = 15
x = 15 / 15
x = 1
Answer:

Sorry for the wait, laptop is being slow :/
I hope this helps.
The first question is to identify a pair of similar triangles. The answer for that would be GCB and BEP. they are not the same size but they do both identify as triangles so that is correct. The next question is explain how you know the triangles in part A are similar. Because they have the same points and when they are reflected they stay the same. Last question is find the distances fromB to E and from P to E. That’s simple. 250 feet and 225 feet. Hope this helps!
It’s already in it’s simplest form!
