The manager of a furniture factory finds that it costs $2200 to manufacture 100 chairs in one day and $4000 to produce 300 chair

s in one day. (A) Assuming that the relationship between cost C and the number of chairs produced x is linear, find an equation that expresses this relationship.

C - cost;  x - the number of chairs produced;
Linear equation: y = m x + b  ( m = ?, b = ? )
2200  = 100 m  + b  / * ( -1 )(we will multiply both sides of the equation by -1) 
4000 = 300 m + b
--------------------------
- 2200 = - 100 m - b
+
 4000 =  300 m + b
----------------------------
1800 = 200 m
m = 1800 : 200 ,  m = 9 ( we will then plug in the first equation )
2200 = 9 * 100 + b
2200 = 900 + b
b = 2200 - 900,  m = 1300
Answer:  C = 9 x + 1300

(b)The graph of y = g(x) is shown. Draw the graph of g(2x). Will award 100 Brainly points
ivanzaharov [21]

Using the stated transformation, the graph of g(2x) is given at the end of the answer.

<h3>Horizontal stretch and compression</h3>

An horizontal stretch or an horizontal compression happens when a constant is multiplied at the domain of the function, as follows:

g(x) = f(ax).

The definition of stretch or compression depends on the value of the constant a, as follows:

  • If a > 1, it is a compression by a factor of 1/a.
  • If a < 1, it is a stretch by a factor of 1/a.

In this problem, the rule is:

f(x) = g(2x).

Meaning that f(x) is an horizontal compression by a factor of 1/2 of g(x), and then the vertices are given as follows:

  • (0,0).
  • (1,-4).
  • (2,-2).

That is, in each vertex, the x-coordinate was divided by 2, and thus the graph with these vertices is given at the end of the answer.

What is the 82nd term of the sequence below?
AlexFokin [52]
The rule to find the term is: y=225-4x
you want to know the 82nd term which occurs when x=82 therefore
y = 225-(4 x 82) = -103


82nd term = -103

-12.11-10.5=75.6-3.5x
Inessa [10]

Answer:

x = 28.06

Step-by-step explanation:

-12.11-10.5=75.6-3.5x

Put all the integers on one side and X on the other.

-12.11 - 10.5 - 75.5 = -3.5x

-98.21 = -3.5x

-98.21/-3.5 = x

x = 28.06
