The answer is -8 because if you do the math
Answer:
A. (-7 -2)
Step-by-step explanation:
You can eliminate y by multiplying the first equation by 7 and subtracting 6 times the second equation:
7(-3x +6y) -6(5x +7y) = 7(9) -6(-49)
-21x +42y -30x -42y = 63 +294 . . . . eliminate parentheses
-51x = 357 . . . . . . . . collect terms
x = -7 . . . . . . . divide by -51. This matches answer choice A.
2(x+1)(x- 6) this is probably correct
The easiest way to graph this equation is using the x and y intercepts. Plug zero in for x to solve for y, then plug zero in got y to solve for x.
