The average rate is 150 cc/4 hrs=37.5 cc per hour.
To find the inverse,
First, you would have to switch the domain and range. In other words, swap x and y:
h(x) = 3/ -x-2
y = 3/ -x-2
x = 3/ -y-2
Then, when you have this, simply solve for y:
x = 3/-y-2
x (-y-2) = 3/-y-2 (-y-2)
x(-y-2) /x= 3 /x
-y-2 = 3/x
-y = 3/x + 2
y = -3/x -2
So the inverse would be
h⁻¹(x)= -3/x -2
Answer:
Yes
Step-by-step explanation:
Given
GH:

Required
Can EF be

First, we determine the slope of GH

Solve for 6y

Solve for y


An equation has the form:

Where

By comparison:

Next, determine the slope of EF

Make y the subject

The slope is:

Compare the slopes of both lines.

Since they have the same slopes, then the equation of EF is possible
It would be: $60.00 - ($46.42+$21.05)
$60.00 - $67.47 = -$7.47
<span>Answer: All rational equations don’t necessary have a single solution however they do have solutions that can’t fulfill the answer. Any solution where the denominator is equal to zero results in an undefined equation.</span>
