We can see that for every 1 hour he increases 10 miles in his distance, so we can say it's constant, he started at 0 and increased 10 miles per hour.
Alternative C.
<u>Answer:
</u>
The value of the exponential expression
is 2
<u>Solution:</u>
16 superscript one-fourth= 
As per the problem,
We have to find the value of
16 in terms of 2 can be written as 
= 
=
As per the exponential rule, 
=
Here, 
= 
= 2
Hence, the value is 2.
To solve for x you need to get it by itself
start by subtracting y
3/4x=e-y
then divide by 3/4 or multiply by 4/3
so, x=(4(e-y))/3
distribute
x=(4e-4y)/3 or x=4/3e-4/3y
I think the answer is 14 6/3
