What values of x make the equation x^2 + 9x – 22 = 0 true? check all that apply.

–11

–2

0

2

11

x = 2 , - 11.

Step-by-step explanation:

Given  : x² + 9x – 22 = 0

To find : What values of x make the equation.

Solution : we have given  x² + 9x – 22 = 0

On factoring

x² + 11x - 2x – 22 = 0 .

Taking common x from first two term and -2 from last two terms.

x ( x +11) - 2 (x +11) = 0.

On grouping

(x -2) (x +11) = 0

For

x - 2  =0

x = 2 .

For

x + 11 = 0

x = -11.

Therefore, x = 2 , - 11.

b) k’(6, 4); l’(3, 3)

step-by-step explanation:

a 270° clockwise rotation maps every point (x, y) to (y, -x). (it negates the x-coordinate and then switches it and the y-coordinate.)

this means the endpoints of the side congruent to kl, k' and l', would be mapped as:

k'(-4, 6)→(6, 4)

l'(-3, 3)→(3, 3)

i'm assuming that it's c.)   volcanoes built the mountains and earthquakes tore them down.
