Laney is ordering books while she is on summer vacation. Reader's Book Club charges $4.00 per book and requires a one-time membership fee of $12. Perfect Pages requires no
membership fee and charges $7.50 for each book ordered. The cost for Laney to order books
depends on the number of books ordered, b. Which inequality can be used to find the
minimum number of books that can be ordered so that the cost of ordering books from
Reader's Book Club is less than the cost of ordering books from Perfect Pages?

step-by-step explanation:

answer: c

substitute in the values.

for a:

f(0) = 0 + 9

f(0) = 9

a is a solution.

for b:

f(7) = 14 + 9

f(7) = 23

b is a solution.

for c:

f (3) = 6 + 9

f(3) = 15

c is not a solution. it's supposed to be 14.

for d:

f(2) = 4 + 9

f(2)= 13

d is a solution.

b: y = 2x + 2

step-by-step explanation:

y = 2x + 1

we want a line that is parallel, so it will have the same slope

the line is in the form y= mx+b, so the slope is 2

we have a slope and the y intercept (0,2)

since x is 0 we know the y point which is the y intercept

we can use y= mx+b to write the equation of the line

m is the slope and b is the y intercept

y = 2x +2
