Max and pedro both clean pools. Each charges a flat fee to clean a pool. Max cleans 12 pools in 8 hours and earned $270. Pedro c
marshall27 [118]

Answer:

The number of pools clean per hour is 1.5

Step-by-step explanation:

Given as :

The number of pools clean in 8 hours = 12

The number of pools clean in 7.5 hours = 9

Let The number of pools they clean per hours = x

I.e x = \frac{8}{12} +  \frac{7.5}{9}

Or, x =  \frac{24+30}{36}

Or, x =  \frac{54}{36}

∴   x =  \frac{3}{2}

I.e x = 1.5

Hence The number of pools clean per hour is 1.5 Answer

Which of the following is a point-slope equation of a line that passes through the points (-1,4) and (8,-2)
dexar [7]

Answer:

y = (2/3)x + 4 2/3

Step-by-step explanation:

For reference, a linear function has an equation of y = mx + b

The first thing we're going to do is use the slope formula, \frac{y2-y1}{x2-x1} or rise over run. In this case that looks like:

(-2-4) - (8 - -1)

-2 -4 comes out to - 6, and the denominator comes out to 9.

6/9 is equal to 2/3, which is our m or slope value.

Next we want to find the b value, or our y-intercept. To do that we'll plug one of the points into the equation with our new-found slope:

4 = (2/3)-1 +b

4 = -2/3 + b

4 2/3 = b

That means our complete equation is:

y = (2/3)x + 4 2/3

OR

y = (2/3)x + 14/3 (equivalent but an improper fraction rather than a mixed fraction).
