Answer:
7.
Step-by-step explanation:
9y+12=75
subtract 12 from 75
divide by 9y
X=3
Just look at where the two lines intercept and see the x value
Simple....
you have:
5x+2=4x-9
5x+2=4x-9
-4x -4x
x+2=-9
x+2=-9
-2 -2
x=-11
Thus, your answer.
Answer:
B = ±X
Step-by-step explanation:
A^2 + B^2 = A^2 + X^2
Subtract A^2 from each side
A^2-A^2 + B^2 = A^2-A^2 + X^2
B^2 = X^2
Take the square root of each side
sqrt(B^2) = ±sqrt(X^2)
B = ±X
I believe it should be alternate interior angles
