Find the difference:

(be sure to put your answer in standard form with the highest degree in front in the numerator)

Find the zero of the function:

(if your answer is a fraction, input the fraction NOT the decimal)

HINT!!!...set y = 0 then solve for x...note this does NOT follow the rules for rational functions

(this is NOT p(x)/q(x)) since there's an extra -2 at the back of the equation)...just sub a 0 in for y and solve for x here to find the zero.

Wind chill factor (W) varies directly with temperature (T) and inversely with the wind velocity (v). If k is the constant of proportionality, write an equation to represent this relationship:

Suppose y varies jointly with x and z. When y = 50, x = 2, and z = 1.5. What is the value of x when y = 35 and z = 4?

input your answer as a simplified fraction

What type of variation is shown the following equation? (direct, joint or inverse)
