Solve appropriate word problems by modeling them with linear equations in two variables.
Nesterboy [21]

<em><u>The cost of production equation is:</u></em>

C = 10n + 20000

<em><u>Solution:</u></em>

<em><u>The equation representing the cost, C, of producing n tires at Royal Tires Co. can be written as:</u></em>

C = mn + f

Where,

C = cost

n = number of tires

f = company's fixed cost

<em><u>It costs $30,000 to produce 1,000 tires while it costs $50,000 to produce 3,000 tires</u></em>

Therefore,

30, 000 = m(1000) + f

50, 000 = m(3000) + f

Which is,

1000m + f = 30000 ------- eqn 1

3000m + f = 50000 ------- eqn 2

Subtract eqn 1 from eqn 2

3000m + f = 50000

1000m + f = 30000

( - ) -------------------

2000m = 20,000

m = 10

Substitute m = 10 in eqn 1

1000(10) + f = 30000

f = 30000 - 10000

f = 20,000

Thus the equation is:

C = 10n + 20000

Examples: Determine if the graph is a function. If it is, state the domain and range.
NemiM [27]

Answer:

Another way to identify the domain and range of functions is by using graphs. Because the domain refers to the set of possible input values, the domain of a graph consists of all the input values shown on the x-axis. The range is the set of possible output values, which are shown on the y-axis.Jan 8, 2019

lukranit [14]
You would take 175 and multiply it by 0.20 which is 35. The you would subtract 35 from 175 because it is marked down so you would get 140. Next, you would take 140 and multiply it by 0.10 and get 14. Finally subtract 14 from 140 to get your answer which would be $126.
