A cyclist rode 3.75 miles in 0.3 hours. How much of an hour will it take her to go 4.5 miles?

It will take her 0.75 an hour to go 4.5 miles.

Step-by-step explanation:

I did 4.5-3.75=0.75. To check if that is right you would need to do 3.75+0.75=4.5.

3; 9 is 8 to -4

step-by-step explanation:

step-by-step explanation:

to determine whether a given function is even, we simply substitute x with -x in the expression. if the result after simplification is identical to the original equation, then the function is said to be even other wise odd.

f(-x) = (-x)^2 - (-x) + 8

      = x^2 + x +8

the resulting function is not identical to the original one;

f(-x) ≠ f(x)

therefore, f(x) is not an even function
