Answer:
Step-by-step explanation:
The form of the equation you are given is called "point-slope" form. The "slope" in this case is the per-hour fee. The point is (9 h, $195). Point-slope form generally looks like this:
y -k = m(x -h) . . . . . line with slope m through point (h, k)
Here, you have m=15, (h, k) = (9, 195), so the equation looks like ...
y -195 = 15(x -9)
__
The "one-time fee" is the cost when hours are zero.
y -195 = 15(0 -9)
y = 195 -9(15) = 60 . . . . add 195 to both sides, and evaluate
The one-time fee is $60.
The answer would be a. Yes, the student’s answer is
reasonable.
In the problem, it states that Cindy rode her bike for an
hour and ran for an hour. Without the
presence of the comma between rode her bike for an hour, and ran for an hour,
this just means that Cindy only rode her bike and ran it for an hour.
The sentence can be written as Cindy rode her bike and ran
for an hour. So, this gives an answer
that Cindy only exercise for an hour.
