Two taxi services charge different rates. Taxi A charges $0.70 per mile
traveled plus an initial charge of $3.00. Taxi B charges $0.90 per mile
traveled. The situation is modeled by this system, where x is the number of
miles traveled and y is the charge for that distance, in cents:
y = 70x + 300
y = 90x
How many miles must each taxi travel for the charges to be equal, and what
is the charge for that distance?
A. Each must travel 9 miles, and the charge is $8.10.
B. Each must travel 10 miles, and the charge is $10.00.
C. The charges will never be equal no matter how far each travels.
Answer:
none of the above
Step-by-step explanation
70x + 300 = 90x
300 = 20x
15 = x
Answer:
each must travel 15 miles, and the charge is $13.50

f(x) = x + 4 g(x) = 3x ^ 2 - 7 Find (fg)(x) .
Answer:
Step-by-step explanation:
(fg)(x) )
[tex](x+4)*(3x^{2} -7)[/tex]=[tex]3x^{3} -7x+12x^{2} -28[/tex] = [tex]3x^{3} +12x^{2} -7x-28[/tex]
Composite functions are functions that are gotten from combining multiple functions.
The value of the composite function (f o g)(x) is 3x^2 -3.
The functions are given as:
[tex]f(x) = x + 4[/tex]
[tex]g(x) = 3x^2 - 7[/tex]
To calculate the composite function (f o g)(x), we make use of:
[tex](f\ o\ g)(x) = f(g(x))[/tex]
We have:
[tex]f(x) = x + 4[/tex]
Substitute g(x) for x
[tex]f(g(x)) = g(x) + 4[/tex]
Substitute [tex]g(x) = 3x^2 - 7[/tex]
[tex]f(g(x)) = 3x^2 - 7 + 4[/tex]
[tex]f(g(x)) = 3x^2 -3[/tex]
Recall that:
[tex](f\ o\ g)(x) = f(g(x))[/tex]
So, we have:
[tex](f\ o\ g)(x) = 3x^2 -3[/tex]
Hence, the value of the composite function (f o g)(x) is 3x^2 -3.

A Sandra and Ben used gasoline at the same rate because - 15
B Sandra and Ben used gasoline at different rates because Ben drove a longer distance.
C Sandra and Ben used gasoline at the same rate of 12 miles per gallon.
