Answer:

y = 3/4x -3

Step-by-step explanation:

$3x-4y=12\\$

Move 3x to the right and change its sign

$-4y = -3x+12$

Divide both sides of the equation by -4

$\frac{-4y}{-4} =\frac{-3x}{-4} + \frac{12}{-4} \\\\y = \frac{3}{4} x -3$

Factor completely x3 − 2x2 − 5x + 10.

Akimi4 [234]

Answer:

(x-2) (x^2 -5)

Step-by-step explanation:

x^3 − 2x^2 − 5x + 10

We will factor by grouping

Take and x^2 out of the first two terms and -5 out of the last two terms

x^2 (x-2) -5(x-2)

Now we can factor out (x-2)

(x-2) (x^2 -5)
