What is being asked here? Are they asking for the passing grade or the total with all the other 90 points added? I think it is A, 90%
2y/5 is the same thing as 2/5 times y so
14=2/5(y) then you divide both sides by y and you get
14/y=2/5 then from there multiply both sides by 1/14 to get
y=0.03
Answer:
The value of f(3)=12.4
Step-by-step explanation:
Average rate of change = 3.4
Interval: -2 < x < 3
f(-2) = 9
We need to find f(3)
The formula used to calculate Average rate of change is: 
here we have a=-2 and b=3
Now finding f(3)

So, The value of f(3)=12.4
