Step-by-step explanation:
B
Answer:
x = 9b/C
Step-by-step explanation:
Cx – 4b = 5b
Add 4b to each side
Cx – 4b+4b = 5b+4b
Cx = 9b
Divide by C
Cx/C = 9b/C
x = 9b/C
Answer:
63
Step-by-step explanation:
Put the given value where x is in each function definition and do the arithmetic. 5 replaces x in F(x); 6 replaces x in G(x).
F(5) + G(6) = (5² +5·5) + (2·6 +1) = 25 +25 +12 +1 = 63
