Let x represent the amount of E6 mixture (in gal) containing 6% ethanol. 4500 gal is the amount of E10 mixture containing 10% ethanol.
Therefore,
is the amount of the resulting E9 mixture containing 9% ethanol.

answer: 1) twenty-seven times y

              2) twenty-seven multiplied by y

hello i am doing good for you that it's summer in your country or state ; )

btw in my country we just have sun and rain as (because i live in the caribbean lol)

also, thx a lot for the points : )

1 number

if we use a graphing calculator, there is only one such number that satisfies the conclusion of the mean value theorem, that is, a number such that

where the right-hand side is the average rate of change of f on the interval [0.5,0.75], which is the slope of the secant line.

in the attached graph, the black line is the secant line which has its slope as the average rate of change of f on [0.5,0.75], while the orange line is the only tangent line to the graph of f in the interval that satisfies the mvt conclusion.
