Answer:
Cost function = 40a + 500
Cost of 90 articles = $4,100
Step-by-step explanation:
The fixed cost is $500 and it will.not change regardless of production level.
The Variable cost is $40 and increases by every additional unit produced.
Assume the number of articles produced is a.
Cost function would be:
Total cost = Variable cost * Number of articles + Fixed cost
TC = 40a + 500
Using this, the cost of 90 articles is:
= 40 * 90 + 500
= $4,100
Answer:
x = 10 Perimeter: 129
Step-by-step explanation:
FINDING X:
4x+7 = 5x -3
7 = x -3
10 = x
x = 10
PERIMETER:
4x + 7 + 5x - 3 + 4x - 5
Combine the "x" values
13x + 7- 3 - 5
Combine the numbers
13x - 1
13(10) -1
130 - 1
129
Answer:
slope = - 
Step-by-step explanation:
given f(4) = 6 and f(- 2) = 8 , then 2 points on the line are
(4, 6 ) and (- 2, 8 )
calculate slope m using the slope formula
m = 
with (x₁, y₁ ) = (4, 6 ) and (x₂, y₂ ) = (- 2, 8 )
m =
=
= -
