2, 6, 8) → D
each element in the domain ( - 1, 3, 5) maps to exactly one value in the range (2, 6, 8)
To answer the question above, isolate F on the other side of the equation by multiplying both sides by 9/5. This gives,
(9/5) C = F - 32
Next, transpose -32 to left side.
(9/5)C + 32 = F
Rearrange the equation to give an answer of
F = (9/5)C + 32
This question calls for ratios. Reuben drove 268 miles with 12 gallons. 268 divided by 12 is 
, so he can drive 22 and one third of a mile with one gallon. Multiply that by 9 and you will get 201 miles, which is how much he can drive using 9 gallons of gas
