Solve the equation for y. y-4=1/2(x-8)

All that's necessary is to add 4 to both sides of the equation. This gives

... y = 1/2(x -8) +4

If you like, you can simplify this by eliminating the parentheses and collecting terms.

... y = 1/2·x -4 +4

... y = (1/2)x

your answer is a

step-by-step explanation:

4*4*4*4=256

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.
