Ayearbook printer charges based on the number of pages printed. here is a table that shows the cost of some recent yearbooks.

number of pages 50 100 150 200
cost 1.75 2.55 3.35 4.15

which equation gives the cost, y, in terms of the number of pages, x?

y = 0.016x + 0.95

y = 0.016x + 1.75

y = 0.016x + 48.25

y = 52.6x + 0.95

1 and 2

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.
