Question

A. The equation below can be used to find the length of a foot or forearm when you know one or the other.



(y=length of the foot) = 0.860 • (x=length of the forearm) + 3.302 


If you let y = length of the foot and x = length of the forearm, this equation can be simplified to y = 0.860x + 3.302.
Using this equation, how long would the foot of a person be if his forearm was 17
inches long?

Answer 1

17.922 inches long

Explanation:

y=0.860x + 3.302

y= 0.860(17) + 3.302

y= 14.62 + 3.302

y= 17.922

Hope it helps!!

Answer 2

y = 0.860x + 3.302.......when forearm (x) = 17
y = 0.860(17) + 3.302
y = 14.62 + 3.302
y = 17.922 <===
