I think it’s the first one.
Hope this helps :)
Answer:
c = 40 + 0.79m
Step-by-step explanation:
The base cost is $40.
So we have:
c = 40
Then, since an additional $0.79 is charged for every mile driven, we add:
+ 0.79m
So then our equation is:
c = 40 + 0.79m
where c = total cost
and m = number of miles driven
Answer:
<em> The answer is
x = y</em>
Step-by-step explanation:
We need to find the inverse of the function
y = sinx
Taking
on both sides
y =
sinx
y = x
Substituting x to y and y to x
<em>
x = y</em>
This is the required inverse of the function
The graph of the function and its inverse is symmetric about y = x
<em> The answer is
x = y</em>
