Answer:
x/9 = 1/5
x = 9/5
The least common denominator is 15. The equivalent fractions would be 10/15 and 12/15.
I=prt
I= 400×(4.5/100)×5
I=$90
total 400+90=$490
I=250×(2/100)×5
I=$25
total 250+25=$275
the denominator cannot be zero, because the division by zero is not defined, therefore:
Therefore the domain of (f o g)(x) is:
