Answer:
x - 15 120 9 18 12 33
y - 5 40 3 6 4 11
Step-by-step explanation:
x - 15 120 a a 12 33
y - 5 40 3 6 b d
x = 3y
When y = 5
x = 3y
x = 3 * 5
x = 15
When y = 40
x = 3y
x = 3 * 40
x = 120
When y = 3
x = 3y
x = 3 * 3
x = 9
When y = 6
x = 3y
x = 3 * 6
x = 18
When x = 12
x = 3y
12 = 3y
y = 12/3
y = 4
When x = 33
x = 3y
33 = 3y
y = 33/3
y = 11
The Anwser Is 0.4 Which Is B
Answer:
x= -14
Step-by-step explanation:
-x+8+3x=x-6
2x+8=x-6
2x-x=-6-8
x= -14
The answer is (0,-4),(1,0)
Answer: a) C = 0.126x + 1.5
b) C = 2.382 c) approximately 179 units
Step-by-step explanation: profit P(x), total revenue R(x) and total cost (C) are related by the formulae below.
Profit = total revenue - total cost
P(x) = R(x) - C
From the question, P(x) = 0.084x - 1.5, R(x) = 0.21x.
Question a)
C = R(x) - P(x)
C = 0.21x - {0.084x - 1.5}
C = 0.21x - 0.084x + 1.5
C = 0.126x + 1.5
Question b)
If C = 0.126x + 1.5, then C at x = 7 units is gotten below as
C = 0.126(7) + 1.5
C = 0.882 + 1.5
C = 2.382.
Question c)
The break even point is the point where total revenue R(x) equals total cost C.
R(x) = 0.21x and C = 0.126x + 1.5
0.21x = 0.126x + 1.5
0.21x - 0.126x = 1.5
0.084x = 15
x = 15/ 0.084
x = 178.57 which is approximately 179 units (since quantity of units can't be decimal)
