Theresa has 50$ in her wallet. the bills are worth either $5 or $1. if there are 18 bills total, how many does she have of each type? A.10 fives and 8 ones B.9 fives and 9 ones C.7 fives and 11 ones D.8 fives and 10 ones HELP!!

D. 8 * $5 + 10 * $1 = $50

Step-by-step explanation:

You can solve the problem by writing equations, by trial and error, or by using each answer as a guess and seeing if it works.

Let's try the last method.

Each answer has a total of 18 bills, so we can't eliminate any answer on the basis of the total number of bills.

A. 10 * $5 + 8 * $1 = $58

B. 9 * $5 + 9 * $1 = $54

C. 7 * $5 + 11 * $1 = $46

D. 8 * $5 + 10 * $1 = $50

D. 8 * $5 + 10 * $1 = $50

If you specifically need to solve with equations, let me know, and I'll show that method to you.

no oblique asymptote

step-by-step explanation:

to find the oblique asymptote of f(x)

here numerator has degree 1 and denomintor degree 2

degree of numerator < degree of denominator

hence there is no oblique asymptote

when the degree of the denominator > that of the numerator, we saw that the value in the denominator got so much bigger, so quickly,   giving us a horizontal asymptote of the x-axis. or we can write

f(x) = a polynomial of x + a proper fraction.

in this case only we have oblique asymptotes but not when numerator has less degree.
