Step-by-step explanation:

Given

--- Cost

--- Number of shirts

Required

Determine the constant of proportionality

The relationship between y and x is:

Where:

k = constant of proportionality

Substitute and

Divide both sides by 6

The constant of proportionality is 5

it has to have an angle of 90 degrees

x^3-4x^2+3x-2/x^2+1

step-by-step explanation:

factor the numerator and denominator and cancel the common factors
