Choose all the possible solution that makes the inequality statement True x + 15 ≤ 35

O 20, 21, 22

O 18, 19, 20

O -18,-19,-20

O 50, 51, 52

18, 19, 20

-18,-19,-20

Step-by-step explanation:

x + 15 ≤ 35

x ≤ 35 - 15

x ≤ 20

x must be 20 or less than it

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.

look at the picture.

y-intercept for the function on a picture is 4 → point (0, 4).

y-intercept for the function

is for x = 0. substitute:

y-intercept is 8 → point (0, 8).
