Answer:

2x(x + 5)(x - 2y)

Step-by-step explanation:

Given

2x³ + 10x² - 4x²y - 20xy ← factor out 2x from each term

= 2x(x² + 5x - 2xy - 10y)

Factor the first/second and third/fourth terms inside the parenthesis

= 2x(x(x + 5) - 2y(x + 5)) ← factor out (x + 5) from each term in the parenthesis

= 2x(x + 5)(x - 2y)

see below

Step-by-step explanation:

7. f(x) = mx + b; b acts as the vertical shift moving the graph up if b is positive and down if b is negative.

f(x) = x-2 has shifted the graph of f(x) down 2 units.

g(x) = x + 7 has shifted the graph up 7 units.

If f(x) is changed to g(x) the vertical shift has gone from -2 to + 7 or (7-(-2) = 9 units up

8. f(x) = mx stretches the graph by a factor of m if m > 0 and compresses the graph by a factor of m if 0<m<1

f(x) = 3x stretches the graph by a factor of 3.

g(x) = 1/4x compresses the graph by a factor of 1/4
