Mathematics Middle School

So far this semester, Warren is averaging a score of 72 points on math tests, which is 20% lower than his average last semester. What was the average of his scores last semester?

Answers

Answer 1

Answer:

86.4

Step-by-step explanation:

72x.20= 14.4

72+14.4=86.4

I'm pretty sure this is right

Answer 2
86.4
You have to multiply .20 and 72. which equals 14.4. it was 20% lower so u have to add the 14.4 to the 72 which equals 86.4

Hello!

A function will be increasing if the y values are increasing (since this is a function, this will pass the vertical line test, meaning that it is increasing if the y values are increasing).

On interval 1, the function is not increasing since the y value stays constant.

On interval 2, the function is increasing because the y values are increasing.

On interval 3, the function decreases because the y values are decreasing.

On interval 4, the function increases again.

On interval 5, the function stays the same because of its constant y value.

To reiterate, on intervals 2 and 4, the function is increasing.

Hope this helps!
