Answer:
Option 2 gives a better combined mileage.
Step-by-step explanation:
Data provided in the question:
Mileage of SUV = 12 mi/gal
Mileage of hybrid = 55 mph or 55 mi/gal
After tuning the SUV, new mileage = 12 + 1 = 13 mi/gal
Now,
For Option 1:
Average mileage of SUV and the Hybrid = 
= 34 mi/gal
For Option 2:
Mileage of new car = 80 mph or 80 mi/gal
Average mileage = 
= 46 mi/gal
Hence,
Option 2 gives a better combined mileage.
Answer:
(f + g) (2) = -4(f+g)(2)=−4
Step-by-step explanation:
We have the functions
F(x) =-3x^2-2F(x)=−3x2−2 And g(x)=4x+2g(x)=4x+2
We want to find
(f + g) (x)(f+g)(x)
Then
\begin{gathered}(f+g)(x) = f(x) + g(x)\\\\(f+g)(x) = -3x^2-2 + 4x+2\\\\(f+g)(x)= -3x^2 +4x\end{gathered}(f+g)(x)=f(x)+g(x)(f+g)(x)=−3x2−2+4x+2(f+g)(x)=−3x2+4x
finally we find
(f + g) (2)(f+g)(2)
\begin{gathered}(f + g) (2) = -3(2)^2 + 4(2)\\\\(f + g) (2) = -3*4 + 8\\\\(f + g) (2) = -12+ 8\\\\(f + g) (2) = -4\end{gathered}(f+g)(2)=−3(2)2+4(2)(f+g)(2)=−3∗4+8(f+g)(2)=−12+8(f+g)(2)=−4
The interest rate is $54 because it went up $216 in 4 years and 216 divided by 4 is 54.
Answer:
A. 4 games
B. $31
Step-by-step explanation:
Fun guys game rental store:
5 + 6.50x
Game bank:
17 + 3.50x
Where,
x = number of games
For how many games rentals will the cost be the same at both stores?
Equate the charges of both stores
5 + 6.50x = 17 + 3.50x
5 - 17 = 3.50x - 6.50x
12 = 3x
Divide both sides by 3
x = 12/3
= 4
x = 4 games
What is that cost?
Game bank:
17 + 3.50x
= 17 + 3.50(4)
= 17 + 14
= $31
