The answer is B. .875 gallons

25/1=100/x
25x=100
x=100/25=4 gallons

32/1=100/x
32x=100
x=100/32
x=3.125 gallons 

4-3.125=0.875 gallons

We divide 100 miles by each car...100/25 = 4 gallons on that car
                                                     100/32 = 3.125 gallons on this one
subtract the two answers 4 - 3.125 and we get a savings of .875 gallons on 100 miles.

What is the value of f(-4) in the piecewise function f(x)= -x-5 for -5&lt;= x &lt;= -2; -x^2+1 for -2&lt;=x&lt;=2; (x-3)^2+2 for
Alik [6]


We first need to pick the correct piece to use. In this case, we will use f(x) = -x-5 because -5<=-4.

Then, we use direct substitution:
f(-4) = -(-4) - 5
f(-4) = -1
