Z=kx/y

7.9=k11/14

Cross multiply

K11=7.9x14

K =7.9x14/11

K=10.1

........

Z= kx15/22

Z=10.1x15/12

Z=12.625

Identify the oblique asymptote of f(x) = quantity 2 x squared plus 3 x plus 8 over quantity x plus 3.
3241004551 [841]
The oblique asymptote in the slope-intercept form is:
y = m x + b,  where:
m = \lim_{x \to \infty}  \frac{ 2x^{2}+3x+8}{ x^{2} +3x} = 2
b = \lim_{x \to \infty}  \frac{ x^{2} +3x+8}{x+3} - 2 x = \\  \lim_{x \to \infty}  \frac{2 x^{2} + 3 x + 8 - 2 x^{2} -6x}{x+3}= \\  \lim_{x \to \infty}  \frac{-3x+8}{x+3} = -3
Answer:  y = 2 x - 3
