Tamara rewrote the expression 0.2(4+1.4y - 2.1). her steps are shown. step 1: 0.2 (4+1.4y-2.1)
step 2: 4.2 + 1.6y - 1.9
step 3: 4.2 - 1.9 + 1.6y
step 4: 2.3 + 1.6y.
which statement identifies and explains the first mistake tamara made?

it will be a cylinder. with a diameter of 8 and 4 single pieces high

step-by-step explanation:

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.
