Answer:
The answer on A P E X is bal(132)
Find the soluiton
2x+2y=16
3x-y=4
x+y=8
<u>3x-y=4+</u>
4x=12
x=3
3(3)-y=4
9-y=4
y=5
(3,5)
test them to see if get true statment
obviously the first equatons of 1,2,4 work
1 doesn't work
2, works
4. doesn't work
2 is the same as the first except both euations are just doubled
answer is 2
I believe it would be (b) (-2,1)
Answer:
30
Step-by-step explanation:
Simplifying it would make it 3/4b^2. I can't write it down the correct way, but it's three over four times b squared. Unless it's a square root, then things would be different.
