$f(x) = {x}^{2} - x - 6$

$f(x) = (x - 3)(x + 2)$

$0 = (x - 3)(x + 2)$

_________________________________

Hint :

$a \times b = 0$

$a = 0 \: \: \: or \: \: \: b = 0$

_________________________________

Thus ;

$x - 3 = 0$

Add sides 3

$x - 3 + 3 = 0 + 3$

$x = 3$

Or

$x + 2 = 0$

Subtract sides 2

$x + 2 - 2 = 0 - 2$

$x = - 2$

Thus the x-intercepts are (( - 2 )) and (( 3 )) .

HELP ME OUT !!! im stressing out keep getting it wrong

Arlecino [84]

Answer:

x=24, y = 33/360 π×24^2/(sin^2(33° (degrees)))

Step-by-step explanation:

notice that x = MK = HM = 24.

Let the center of the circle be C.

Also, notice the radius of the circle can be expressed as the hypotenuse of HMC. Using some trig, we figure out that the radius is 24/sin(33 degrees).

Using the radius of the circle, we can figure out the circumference. The circumference is pi*r^2=(24/sin(33 degrees))^2*pi=pi*24^2/(sin(33 degrees)^2)

Lastly, notice that y = 33/360*circumference = 33/360 π×24^2/(sin^2(33° (degrees)))

hopefully this helped

-10x - 135 = 117 + 2x A. 25 B. -18 C. -21 D. 22 Helps pls

Lina20 [59]

Answer:

Step-by-step explanation:

Add 10x to both sides:

-10x - 135 = 117 + 2x

-10x - 135 + 10x = 117 + 2x + 10x

-135 = 117 + 12x
