Answer:
D. Both functions are decreasing at the same average rate on that interval
Step-by-step explanation:
The dashed lines on the attached graph of the two functions (f in red, g in purple) represent the average rate of change of each function on the interval. The lines are parallel, because the average rate of change is the same for each of the functions on that interval.
__
Function f decreases by 60 units from f(0) = 64 to f(4) = 4 on the interval x = [0, 4]. Function g decreases by 60 units from g(0) = 75 to g(4) = 15 on the same interval. The average rate of change is the amount of decrease divided by the interval width. Those values are the same for both functions.
Hi so have you heard of KFC? It stands for keep flip change. You use it when adding or subtracting or when you're dividing fractions. So you keep the first part of the problem the same; you flip the sign of the second part, and change the sign of the third part. So -23.9- -9.3 becomes -23.9 + +9.3. So take away 9.3 from 23.9 and get 14.6. Whenever you add a positive to a negative like we do here, the answer will become a smaller negative number if the positive number is "smaller" than the negative number.
Answer:
The answer is C
Step-by-step explanation:
Hello!
First we have to define a variable.
Let x stand for the price of a granola bar
Then we have to make our equation
1250x + 25 = 800
This is the equation because the price for all the granola bars and delivery was $800
Now we solve it
Subtract 25 from both sides
1250x = 775
divide 1250 from both sides
x = 0.62
The cost for a granola bar is $0.62 or 62 cents
Hope this helps!
Answer:
The linear function is 
.
Step-by-step explanation:
A linear function is given by the formula,
, where m is the slope and c is the y intercept of function.
The following two points lie on the graph; (0,-1) and (3,-10)
Inserting this two points we get,
,
solving this two equations we get,
m = -3 and c= -1
Thus, the linear function is given by,
