Answer:
(0, 1)
Step-by-step explanation:
The correct answer is B
To find the average we add all the given numbers together then divide by how many numbers there are.
A is 7
B is 8
C is 9
M(x) = 5x + 4 n(x) = 6x - 9
Part 1 (m + n)(x) = 5x + 4 + 6x - 9
= 11x - 5
Part 2 (m * n)(x) = (5x + 4)(6x - 9) = 30x^2 - 21x - 36
Part 3 m[n(x)] = 5(6x - 9) + 4
= 30x - 45 + 4
= 30x - 41
