What would be the projected value of x

D 13

Step-by-step explanation:

y = 3.5x -4

Let y=41.5

41.5 =3.5x -4

Add 4 to each side

41.5 +4=3.5x -4+4

45.5 = 3.5x

Divide each side by 3.5

45.5 /3.5 = 3.5x/3.5

13 =x

step-by-step explanation:

i have done this all on a piece of paper but idk how to put it on here cuz it needs to be drawn

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.
