Answer:
<em>(f-g)(x)=x+14</em>
Step-by-step explanation:
<u>Operations with Functions</u>
Given two functions f(x) and g(x), the following operations are defined:
(f+g)(x)=f(x)+g(x)
(f-g)(x)=f(x)-g(x)
(f*g)(x)=f(x)*g(x)
(f/g)(x)=f(x)/g(x)
We have f(x)=3x+10 and g(x)=2x-4. Use the second formula to find
(f-g)(x)=(3x+10)-(2x-4)
Operating:
(f-g)(x)=3x+10-2x+4
Joining like terms:
(f-g)(x)=x+14
First, we must find common denominators in order to subtract the terms. we can multiply 8/9 by 2/2 and 1/2 by 9/9.
we get:
16/18-9/18
16-9= 7 and we keep the same denominators, so our final simplified answer is:
7/18

Oops someone else answered it before me
Answer:
Her new balance is Zero
-$27 + $27 = $0
Step-by-step explanation:
She has a debt of 27$ (-27 $).
If she goes to the bank to deposit 27$ (+27$)
Then, her balance would be
-$27 + $27 = $0
