The cost function, C(x) in terms of x, the number of refrigerators manufactured is written as C(x) = 1665 + 100x
The given parameters;
- total cost of manufacturing 160 refrigerators = $17665.
- total cost of manufacturing 182 refrigerators = $19865.
- total cost, C, is linearly related to the number of refrigerators, x
The linear equation is set up as follows;
C = b + ax
where;
- a is cost per refrigerator
First equation;
17665 = b + 160a -------(1)
Second equation;
19865 = b + 182a -----(2)
subtract equation 1 from equation 2 to solve for the value of a;
2200 = 22a
Solve for the value of b;
17665 = b + 160(100)
17665 = b + 16000
b = 17665 - 16000
b = 1665
<em>C(x) = b + ax</em>
<em>C(x) = 1665 + 100x</em>
<em />
Thus, the cost function, C(x) in terms of x, the number of refrigerators manufactured is written as C(x) = 1665 + 100x

Angles could be expressed in degrees or in radians. The relationship between the two could be easily explained by illustrating a circle. A semi-circle has a total angle of 180°. This is equal to a π radians. So if the angle is π/2, in degrees, that would be 180/2 = 90°.
Then, determining the cosine 90° in a calculator would yield an answer of zero.
Maria = x
Tom = y
Use substitution
x+y=30
2y=x
2y+y=30
3y=30
y=10
Tom is 10 years old.
x+y=30
x+10=30
x=20

Answer:
slope = 
if it were in an
Step-by-step explanation:
the graph is a negative and will therefore have a negative slope. to find the slope, pick a point on the graph and find the 
.
for instance, start with the point (0,1). Then go down 1 and left 2 to get to the next point on the graph (2,0). 1 is the "rise" and 2 is the "run" hence -1/2 being the slope.
you could also use the slope formula: 
point 1: (0,1) (x₁ ,y₁)
point 2: (2,0) (x₂ , y₂)
Bottom right! You are correct. :)
