Peter is an artist, and he charges for his paintings on an hourly basis. He also receives tips from many of his clients. The scatter plot below shows the number of hours Peter
worked on a painting and the amount of money he received from his client. A line of
best fit for these data points, the equation y=85x+20, is also shown on the plot.

On average, how many more dollars does a client pay for a painting that takes 4 hours
than a painting that takes 3 hours?

we have three similar triangles, because each has a right angle and shares an angle.   let's write the angles in order: opposite to short leg, long leg, hypotenuse.

cab similar to bad similar to cbd

or as ratios,

ca: ab: cb = ba: ad: bd = cb: bd: cd

we also know

ac = ad + cd

(ad+cd): ab: cb = ba: ad: bd = cb: bd: cd

(ad+cd)/cb=cb/cd

we have cb=6, ad=5 and seek x=cd.

we reject the negative root and conclude x=4

answer: 4

168

step-by-step explanation:

first off, we know that he drove 3.5 hours at a rate of 48 mph.

knowing that, we want to see how many miles he drove all-together.

in this case, we can just multiply 48 by 3.5.

48 * 3.5 = 168

think the answer is 30 degrees. if not than it is 20 degrees. not 100% sure. let me know if it was right.

step-by-step explanation:

simple you would first have to get   a negative number where as 1 to be multiplied by 24 and then you would have to multiply 6 time 4 and then repeat that process until you reach your term
