Answer:
C.60
Step-by-step explanation:
Just multiply 300 by 9 and then divide by 45.
f(10) means to input x = 10 into the function.
From inspection of the given function:
the "10" is the numerator of the fraction.
Therefore, swap the "10" for "x" to give the function in terms of x:
k-1/2b=47 because the difference is subtraction and half b is a half fraction and it equals 47.
