Suppose Lin labels the books at a constant speed of s books per minute. There can be several equations written that represent the relationship between her labeling speed and the number of minutes it would take her to finish labeling. Complete the equation below: m = where m is the number of minutes and s is the speed in books per minute.

Step-by-step explanation:

Given

Required

Determine the expression for s

The speed is calculated as:

Substitute S for speed

Let the number of books be b and the time be m.

The expression becomes

Hence, the expression for the scenario is:

answer:     true

step-by-step explanation:

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.
