Answer:

D. (x – 3)^2 = 17

Step-by-step explanation:

We assume you want an equivalent to x^2 -6x = 8.

We can complete the square by adding the square of half the x-coefficient to both sides of the equation.

x^2 -6x +(-6/2)^2 = 8 +(-6/2)^2

(x -3)^2 = 17 . . . . simplify

PLEASE Solve y=-2.4x+8.2

frez [133]

$x = - \frac{41}{12} + y \times \frac{5}{12}$

Step-by-step explanation:

$y = 2.4x + 8.2$

move 2.4x to the left-hand side and change its sign.
move y to the right-hand side and change its sign.

$- 2.4x = 8.2 - y$

Divide both sides of the equation by -2.4

$\answer$

$x = - \frac{41}{12} + y \times \frac{5}{12}$
