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?

  or  

step-by-step explanation:

if the four friends split the cost, p, of the pizza evenly, then each friend pays one-fourth of the cost of the pizza.

the expression is   or  

y = 5x + 17

step-by-step explanation:

a perpendicular line will be the opposite reciprocal slope of the given equation.   the slope given is -1/5 so the opposite reciprocal is 5

find b:

7 = 5 (-2) + b

7 = -10 + b

17 = b

write equation

y = 5x + 17

1/3 + 1/3 ≠ 2/6 because 1/3 alone = 2/6  

step by step explanation:

1/3 + 1/3 = 2/3       2/3=4/6
