Lia must work at least 5 hours per week in her family’s restaurant for $8 per hour. she also does yard work for $12 per hour. lia’s parents allow her to work a maximum of 15 hours per week overall. lia’s goal is to earn at least $120 per week.
write a inequality with r repenting for hours working at the restaurant and let y be the hours of yard work.

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.
