Redued by 15%
orignal=100%
decrease by 15%=100%-15%=85%
find 85% of original
orignal=15 feet
85% of 15=0.85 times 15=12.75 feet
answer is B
If you are trying to figure out how much it will cost:
8 x 4 = 32
Cost of gas = $32
2x^3-2x^2+3x^2-3x-6x+6
2x^3+x^2-9x+6
Answer:
Check below
Step-by-step explanation:
Hi,
We're dealing with linear functions. 
We have here the first function.

That's a linear function, with slope, and no linear coefficient since
But on the other hand, the functions below, they all describe parallel lines, since their slope has the same value. I've changed the letters to make it easier the comprehension.
Even though each one has the same slope value, they have different non zero linear coefficients, {-6,-18,6,18}. Unlike, the first one

A possible solution would be adjusting any of these, whose operation would result in g(x)=3x, but
