During a scuba dive, Lainey descended to a point 17 feet below the ocean surface. She continued her descent at a rate of 17 feet per minute. Enter an inequality you could solve to find the number of minutes she can continue to descend if she does not want to reach a point more than 89 feet below the ocean surface. Use t to represent the variable for the minutes Lainey can continue to descend.

the answer

b. they are parallel and will never intersect.

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.
