Given the following question:
To find the answer to this question we will use the formula to calculate distance.
(6, 5) = (x1, y1)
(-3, 1) = (x2, y2)
Which means the distance between the two points is "5 units."
Hope this helps.
if i remember correctly with perpendicular stuff you just take away the negative
you have to subtract the amount of money chuck earned ($72.50) by the cost of the gas for the mower ($11.25) and the new string for the trimmer he bought ($7.75).
and then subtract $61.25 by the second thing he bought (the new string for the trimmer)
so in total it's $53.50 (53 dollars and 50 cents)
