Answer:
7) (f+g)(x) = 4^x +5x -5
8) (f-g)(x) = 4^x +x +5
Step-by-step explanation:
7) add the two expressions.
(f+g)(x) = f(x) +g(x) = (4^x +3x) +(2x -5)
(f+g)(x) = 4^x +5x -5
__
8) subtract g(x) from f(x).
(f-g)(x) = f(x) -g(x) = (4^x +3x) -(2x -5) = 4^x +3x -2x +5
(f-g)(x) = 4^x +x +5
Answer:
Yuhh the answers c dawhggg trus me i just did the same thing lawl!
Step-by-step explanation:
Answer:
the terms are 400n , 62n 120 and 8n
the number of coefficients is 3
equa expression is 346n+120
Step-by-step explanation:1
Combining like terms 400n400n and -62n−62n
338n+120+8n
338n+120+8n
2 Combining like terms 338n338n and 8n8n
346n+120
346n+120
For the rest of them i just counted.
