2(4n - 5) +3 Simplify each expression. I need you guys to explain step by step so i can understand please!

8n-7

Step-by-step explanation:

distribute the 2 so you get 8n-10

then you add 3 to negative 10 and you get negative 7

- (2, -7)

- lines r and s and lines t and u must be parallel

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.
