The expression would be: m + 0.15m and to know how much she paid I believe it would be 26.09 (rounded)
Hope it helped!
C= -7 because 63 divided by 9 is seven. Since there is only one negative your answer will also be negative.
Answer is 30. 3x=90 divide by three to get x =30 to check 90+30+60 equals 180making it a triangle
Answer:
I don't know if your question is multiple choice or not but here's a close estimate to what it should be.
y =
Step-by-step explanation:
Obviously at a drop of 0 height there would be 0 rebound height so your y-intercept has to be 0.
As for the slope of the line I used the point at 2.5 and 3.
Here are the coordinates (2.5, 1.25) and (3, 1.625)
Find the average rate of change as you see below
1.625 - 1.25 = .375
3 - 2.5 = .5
.375 / .5 = .75 or 3x/4
The points aren't exactly on the line and the graph isn't 100% linear so obviously the equation is not 100% precise. The slope should very close to 0.75 or 3/4.
The range of a set of data is the difference between the highest and lowest values of that data set, so subtract 25 from 64, so the range is 39.
