Answer: 7 multiple choice questions and 8 free response questions
Step-by-step explanation: m is the number of multiple choice questions and f is the number of free response questions.
m+f=15
m+2f=23
You can subtract the first equation from the second, and get f=8
m+8=15
m=7

Answer:
f(2) = 9
Step-by-step explanation:
It's give in the question,
Two different functions are,
f(x) = 4x + 1
g(x) = -2x
Then we have to find the output value of function 'f' for the input value x = 2.
By substituting the value of x in the function 'f',
f(2) = 4(2) + 1
= 9
f(2) = 9
