Answer:
C
Step-by-step explanation:
9x² - 4
can be factored as a difference of squares , that is
(U + V)(U - V)
9x² - 4
= (3x)² - (2y³)²
with U = 2x and V = 2y³
Explanation:
All values in the x-column get filled with -2.
The graph is the vertical line, x = -2.
__
You are told x=-2. There is nothing to figure out. The value of y is irrelevant.
That equation describes a vertical line. The points on the line have x-coordinate -2, and any (every) y-coordinate.
Answer:
May: $23.25
Inez: $2325
Jo: $232.5
Step-by-step explanation:
Inez makes 100 times as much as May. Since May makes $23.25, move the decimal point two places to the right to multiply the number by 100. You will get $2325. Jo makes 1/10 of the money Inez makes. Pretend there is a decimal point at the end of 2325. Move the decimal point one place to the left to divide by 10. You will get $232.5.
Answer:
2x - 4
Step-by-step explanation:
2(3x + 6) = 6x + 12
2(-2x - 8) = -4x -16
6x + 12 - 4x - 16 = 2x - 4
