Answer:
(f+g)(x) = x^2 +10x +7
Step-by-step explanation:
(f+g)(x) = f(x) +g(x) = (15x +7) +(x^2 -5x)
= x^2 +x(15 -5) +7
= x^2 +10x +7
Answer:
1 fancy 15 plain
Step-by-step explanation:
F + P = 16
15F +10P = 165
Miltiplu the 1st by -10:
-10F -10P = -160
15F + 10P = 165
Add both (10p is cancelled)
5F = 5
F =1
16-1 = 15 (15plain)
15 x10 =150
1x15 =15
150 +15 = 165
