Two identical jars are filled with equal numbers of marbles. the marbles are colored red or white. the ratio of red to white marbles is 7: 1 in jar 1 and
9: 1 in jar 2. if there are 90 white marbles all together, how many red marbles are in jar 2?

$15.40 per mile

step-by-step explanation:

you have to round up to 4 because 6 is over 5 so you have to round the 3 up to 4

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
