g(n) = 3n³ - 5 h(n) = 2n - 5 (g + h)(2) = g(2) + h(2)
g(2) = 3(2)³ - 5 = 3(8) - 5 = 24 - 5 = 19
h(2) = 2(2) - 5 = 4 - 5 = -1
g(2) + h(2) = 19 + -1 = 19 - 1 = 18
Answer: 18
Answer:
5
Step-by-step explanation:
Let a = number of pieces of chocolate bought by Amin.
Let b = number of pieces of chocolate bought by Bob.
b = 2a
(a - 3)(b - 3) = 14
ab - 3a - 3b + 9 = 14
a(2a) - 3a - 3(2a) = 5
2a^2 - 3a - 6a = 5
2a^2 - 9a - 5 = 0
(2a + 1)(a - 5) = 0
2a + 1 = 0 or a - 5 = 0
a = -1/2 or a = 5
Amin cannot have bought -1/2 pieces of chocolate, so we discard the soluion a = -1/2.
a = 5
Answer: 5
Answer:
I think it is A because 12 is the slope and 3 is just b... try y = mx + b

Answer:
(4, 3 )
Step-by-step explanation:
Given a system of equations graphically, then the solution is at the point of intersection of the 2 lines.
The lines intersect at (4, 3 ) ← solution
