Answer:
7) (f+g)(x) = 4^x +5x -5
8) (f-g)(x) = 4^x +x +5
Step-by-step explanation:
7) add the two expressions.
(f+g)(x) = f(x) +g(x) = (4^x +3x) +(2x -5)
(f+g)(x) = 4^x +5x -5
__
8) subtract g(x) from f(x).
(f-g)(x) = f(x) -g(x) = (4^x +3x) -(2x -5) = 4^x +3x -2x +5
(f-g)(x) = 4^x +x +5
Answer:
60 or 60:1
Step-by-step explanation:
You will have to divide 180 by 3 which is 60 or you can divide 160 / 3 = 60 & divide 3 / 3 = 1.
To answer this you must have 1/4 of tank which is 5 gallons then add 10 to get 15 gallons
Look at the digit one number place to the right of the thousands place, the hundreds. In this case it is another 4. Since it is less than 5, the thousands place will stay the same. If it were 5 or greater, the thousands place would go up by one number. 14,494 rounded to the nearest thousand is 14,000
Since the domain are the x-values of the function, we need to find the y-values using those x-values.
- for x=

,

. Now we have our first ordered pair:

- for

,

which gives us our next ordered pair:

- for x=2,

, so (2,1)
- for x=4,

, so (4,2)
- for x=8,

, so our last order pair is (8,3)
Finally we can plug the points and joint them to create our graph:
