On a two-week job, a repairman works a total of 70 hours. He charges $75 plus $40 per hour. An equation shows this relationship, where x is the number of hours and y is the total fee. A. Which number is the slope of the line shown by the equation?
B. Which number is the y-intercept?

m = 40

b = 75

If he charges $75, that is an initial condition, which won't variate, it's an independent term. Then the problem states that he charge $40 per hour, where hours is define as . If is the total fee, then the equation that model this problem is:

Which is the slope-intercept form

So, the slope is 40, and the y-axis interception is 75. That is

step-by-step explanation:

x =±sqrt(1/3)

step-by-step explanation:

x+4/6x=1/x

multiply each side by 6x to get rid of the fractions

6x*(x+4/6x)=1/x*6x

distribute

6x^2 +4 = 6

subtract 4 from each side

6x^2 +4-4 = 6-4

6x^2 =2

divide by 6

6x^2/6 = 2/6

x^2 = 1/3

take the square root of each side

sqrt(x^2) = ±sqrt(1/3)

x =±sqrt(1/3)
