I am doing that stuff to but I don’t know sorry but it might be 239
Answer:
27, 20, 60
Step-by-step explanation:
We use the equation
(x) + (x - 7) + (3 * (x - 7)) = 107
= x + x - 7 + 3 * (x - 7) = 107
= 2x - 7 + 3(x - 7) = 107
Add 7 on both sides
= 2x + 3(x - 7) = 114
Expand the 3
= 2x + 3x - 21 = 114
= 5x - 21 = 114
Add 21 on both sides
= 5x = 135
Divide 5 on both sides
= 5x/5 = 135/5
= x = 27
Plug the functions in
(27) + (27 - 7) + (3 * (27-7)) = 107
You would get
27 + 20 + 60 = 107, therefore the numbers are 27, 20, 60
Answer:
D and E
Step-by-step explanation: Math
Answer:
D.
Step-by-step explanation:
The average rate of change of the function f is more than the average rate of change of x.
Here is why.
Look at the rates of change going from x = 0 to x = 3.
From x=0 to x=1, where x changes one unit, the value of f(x) only changes one-half unit, which is less than the change in x. But as you move to the right, see how the change in f(x) keeps getting larger and larger in magnitude? (Don't worry about the (-) sign.)
So, the <u>average</u> change in f will definitely be bigger than the average change in x, over the long run.
Now, look from x =0 and go back the other way, as x decreases 1 unit at at time. It is the same story.
If you would like to see this for yourself, look at the attached graphic.
Hope this helps.
