Answer:
21.00d+0.10m<=115.00
Step-by-step explanation:
d=days m=miles it must be less than or equal to 115 dollars
For this case, we must find the quotient of
divided by
, to verify if Tina was correct.
So:

So, Tina was wrong, she had to divide by 3x.
Answer:
Option B
42 received an A
so 40-42 = 38 did not
the fraction would be 38/80, divide both numbers by 2
38/80 reduces to 19/40 did not receive an A
Answer:
3/4
Step-by-step explanation:
First of all, we need to calculate the slope of the line shown. This can be computed as:

where
is the increment along the y-direction
is the increment along the x-direction
We can choose the following two points to calculate the slope of the line shown:
(-3,2) and (0,-2)
And so, the slope of the line shown is

Two lines are said to be perpendicular if the slope of the first line is the negative reciprocal of the slope of the second line:

Using
, we find that a line perpendicular to the line shown should have a slope of

Independent: cell phone plan
dependent: monthly cost
constant: per month/per minute (money)
