Use the equation below to find y, if m=7, x=6, and b=2.
y=mx+b

y=44

Step-by-step explanation:

y=mx+b you do substition  and replace m with 7 and b with 2 and x with 6

y=7*6+2

the solve with system of order 7 times 6 which is 42 then add the 2 and then you get 44

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.
