we know that
Average Rate of Change. is the change in the y-value divided by the change in the x-value for two distinct points on the graph
So
![A=\frac{(f(b)-f(a))}{(b-a)}](https://tex.z-dn.net/?f=%20A%3D%5Cfrac%7B%28f%28b%29-f%28a%29%29%7D%7B%28b-a%29%7D%20%20)
in this problem
![a=4\\ b=13\\ f(a)=f(4)=8\\ f(b)=f(13)=11](https://tex.z-dn.net/?f=%20a%3D4%5C%5C%20b%3D13%5C%5C%20f%28a%29%3Df%284%29%3D8%5C%5C%20f%28b%29%3Df%2813%29%3D11%20)
substitute the values in the formula above
![A=\frac{(11-8)}{(13-4)} \\ \\ A=\frac{3}{9}](https://tex.z-dn.net/?f=%20%20A%3D%5Cfrac%7B%2811-8%29%7D%7B%2813-4%29%7D%20%5C%5C%20%5C%5C%20A%3D%5Cfrac%7B3%7D%7B9%7D%20%20)
Divide by
both numerator and denominator
![A=\frac{1}{3}](https://tex.z-dn.net/?f=%20A%3D%5Cfrac%7B1%7D%7B3%7D%20)
therefore
the answer is
![\frac{1}{3}](https://tex.z-dn.net/?f=%20%5Cfrac%7B1%7D%7B3%7D%20)
U would multiply your base time your height and then get 24inches
Answer:
y = 2x
Step-by-step explanation:
plug in the x number of scooters to get cost y
multiply by two each time
hope this helps :)
1 penny = 0.005 ft
total amt of pennies = 1264/0.005 = 252800 pennies
Domain is x’s and range is y’s.
For a, the domain is -2<=x<1
For a, the range is 1<=y<2
For b, the domain is 1<=x<=2
For b, the range is -2<=y<=2
(The <= is the ones with a line under, meaning equal to, if that makes sense. So write with a line under rather than equal sign)
Hope this helps!
