Y = 1.6x + 48 Based on the equation, what is the approximate shoe size for a man having a height of 60 inches?

A. 7 1/2
B. 10 1/2
C. 12
D. 14

1

14

Step-by-step explanation:

substitue 60 into 1.6

y = 1.6(60) + 48

96 + 48

144

step-by-step explanation:

once you graph it hit 2nd (the blue button) and graph

that takes you to a table of coordinates

on the left is x coordinates and on the right is y coordinates and an empty box

(you may have to scroll up/down in order to get ( x, 0)

f(x) has value 150 at x= 0

and 0 at x= 3

so d(f(x))/dt = slope = -150/3 = -50
