HELP Please
i actually don’t get question 2 and 3
if anyone knows them please solve it :(

m=slope =5.5

Step-by-step explanation:

(2)

you may choce (c)

y-y1=m (x-x1)

(3)

y-30=5.5 (x-10)

y-30=5.5x-55

move 30 other side

y=5.5x-55+30

y=5.5x-25

step-by-step explanation:

x= -3 and

step-by-step explanation:

to find the roots of a cubic, use division or factoring to find the factors then set equal to 0. as this is a difference of cubes, it factors into

where a is the cube root of .

here   this is 27 and the cube root of 27 is 3. so we write using the form:

.

set each factor to 0 and solve for x.

x-3=0

x=3

the quadratic expression does not factor and must be solved using the quadratic formula.

where a = 1, b=3, and c=9

this cubic has two complex roots.
