1, Predit the total cost if you bought 20 books.
Books Bought 1 3 5 7
Total Amount Spent $ 21 39 57 75


A, $192
B, $420
C, $200
D, $310




2, An equation which represents the average weight in pounds of an adult male of a given height in inches is w = 4.5h - 142. Predict the weight in pounds of an average male with a height of 6' 3" (75 inches). Round to the nearest pound.
A, 168
B, 182
C, 196
D, 212




3, Find the slope for the values in the table below.
x -1 0 1 2
y 5 3 1 -1


A, 1
B, -1
C, 2
D, -2




4, Write an equation for the table.
x -1 0 1 2
y 5 3 1 -1


A, y = -2x + 3
B, y = -x + 3
C, y = 2x + 5
D, y = x + 5




5, Predict the y-value if x = -3.

1) A, each old number of books cost $18. From 7-19 is 6 if you count 7.9.11.13.......6 times 18 + 8, because 19-20 is only 1 book, which is 8 dollars because if 2 books cost 18, one cost 9. add them you get 192.

2)C, 4.5+75-142=195.5 round to 196.

3) If 4 and 5 are right, then 3 should be D. The slope is the number before (x) in y=mx+b

4)A, plug in number and it works.

5)A, plug in number, -2(-3)+3=9

Answer 2

All you do is plug in 75 inches into your weight equation

Answer 3

tell me what you get, and i'll tell you if it's right

Answer 4

4.5*(75)-142

Answer 5

w = 4.5 (75) - 142
w = 4.5* (75) -142
w = 195.5 or 196 to the nearest pound --> C. 196
