Before the work was done, the cost was ...
($4/gal)*(8 gal)/(340 mi) = $32.00/(340 mi)
After the work was done, the cost was ...
($4/gal)*(7 gal)/(350 mi) = $28.00/(350 mi)
The savings is the difference of these costs:
(32.00/340 -28.00/350) $/mi ≈ $0.01/mi
After the mechanic worked on the car, it cost about $0.01 per mile less to run.
We can explicitly find the inverse. If is the inverse of , then
Solve for the inverse :
Then when x = -6, we have
Alternatively, we can first solve for x such that . Then taking the inverse of both sides, . (The difference in this method is that we don't compute the inverse for all x.)
We have
Answer:
-6
Step-by-step explanation:
The opposite value of an integer is the same distance from the origin of the number line as the number, just on the opposite side. So the integer 6's opposite is -6.
