we have

To find the inverse
Step 1
Exchanges the variables, x for y and y for x

Step 2
Isolate the variable y



Square Root both sides

Step 3
Let

so

therefore
<u>the answer is</u>
The inverse is

Answer:
8(15-m)
Step-by-step explanation:
By looking at the options, we can understand that the right one is 8(15-m), since we need to multiply the time by the number of question.
Also, we can check that result by arranging an equations usint the total time.
55 = 3m - 8(15-m)
55 = 3m - 120 + 8m
55 = 11m - 120
55 + 120 = 11m
175 = 11m
m = 175/11 = 15.91
55 = 3*15.91 - 8(15-15.91) = 47.73 - 120 + 127.28 = 55.01 ≈ 55

Answer:
The answer is B) -3 and 1/3
Explanation:
The answer must be between -3 and -4 because that is the location on the plot.
You count two ticks on the plot. The first one is 1/3. The second one is 2/3.
There is no third one because 3/3 would bring you to the next number.
The dot is on the first tick, meaning that it is 1/3. If the dot is between -3 and -4, you can conclude that the answer is -3 and 1/3.
