Answer:
What is the table? what are the values? If you can't insert a picture please type the like f(x)= y
Step-by-step explanation:
Yvaries as x means
y=kx where k is constant
y=2.5
x=6
find k
2.5=k6
divide bot sides by 6
2.5/6=k (leave as that an simplfy later)
if x=4, what is y
y=(2.5/6)*4
y=10/6
y=5/3
y=1 and 2/3
So let's start out by labeling Ethan as X
Since 85 is 1/3 of what Ethan drove, that means Ethan drove 3 times of 85.
85= (3x) -21
85 -21 = 3x
60=3x
20 = x
