Pleeaaaseee i will give brainliest! quick fix inc. repairs bikes. their revenue, in dollars, can be modeled by the equation y=400+220x, where x is the number of hours spent repairing bikes. their overhead cost, in dollars, can be modeled by the equation y=20x^2+160, where x is the number of hours spent repairing bikes. after how many hours does the company break even?

option 1 is correct.

step-by-step explanation:

y varies inversely with x and constant of variation is 4

the equation will be:

y = k/x

where k =4 so,

y = 4/x

if we put values of x of option 1 in the above equation and find values of y

y = 4/-2 => y =-2

y = 4/-1 => y = -4

y = 4/1 => y = 4

y = 4/2 => y =2

so, all the values of x and y are correct.

if we put values of x given in other options and find value of y we cannot find whole table satisfying the equation.

hence option 1 is correct.
