Manuel has $600 in a savings account at the beginning of the summer. he wants to have at least $300 in the account at the end of the summer. he withdraws $28 each week for food. which inequality represents w, the number of weeks manuel can withdraw money while not dropping below a $300 balance?

28-600w < 300

28-600w > 300

600-28w < 300

600-28w > 300

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.

y -5 = (-1/4)(x + 8)
