\frac{2 {x}^{2} - 2x }{x - 1}  \div  \frac{2x + 8}{x - 3}  \\  =  \frac{2x {}^{2}  - 2x}{x - 1}  \times  \frac{x - 3}{2x + 8} \\  =  \frac{(2 {x}^{2} - 2x)(x - 3) }{(x - 1)(2x + 8)}

So:

1) x - 1 ≠ 0

x ≠ 1

2) 2x + 8 ≠ 0

2x ≠ -8

x ≠ -4

For each equation, determine whether it represents a direct variation, an inverse variation, or neither.
Murljashka [212]

Direct variation is written in the form y = k * x or x = y * k. And, inverse variation is written in the form y = k/x or x = y/k.

For the first problem, if we isolated the y, we would get:

4y = 3x - 1

y = (3/4)x - 1/4

This is written as y = mx + b, which isn’t the form of direct or inverse variation, so the answer is NEITHER.

For the second equation, we could divide by 2 on both sides to isolate x and see if it is in the correct form:

x = 4/y

This is inverse form, so the second question is INVERSE with a constant of variation as 4.
