Answer:

( x + 2 ) and ( x - 11 )

Step-by-step explanation:

x² - 9x - 22 = 0

x² + 2x - 11x - 22 = 0

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

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

Factors of x² - 9x - 22 are ( x + 2 ) and ( x - 11 ).

svet-max [94.6K]

Answer:

$m=\frac{1}{2}$

Step-by-step explanation:

defition of slope(m) of a line:

$m=\frac{Y_b-Y_a}{X_b-X_a}$

A=(-1,-5)=(Xa,Ya) then Xa= -1 and Ya= -5

B=(3,-3)=(Xb,Yb) then Xb=3 and Yb= -3

$m=\frac{-3-(-5)}{3-(-1)} \\\\m=\frac{-3+5}{3+1} \\\\m=\frac{2}{4} \\\\m=\frac{1}{2}$
