We want to see which of the listed situations can be modeled with linear equations. We will see that the situations that are linear are:

  • "He sells 5 propane stoves each day for 4 consecutive days"
  • "Cooper's profit decreases by $125 each day for 5 days"
  • "Cooper sells 2 fewer fishing poles each day for 1 week".

<h3>Finding situations that are linear</h3>

First, a linear equation shows a dependence of two variables as:

y = a*x + b

Where y and x are the variables, a is the slope and b is the y-intercept.

Let's see which situations can be written in this form.

"He sells 5 propane stoves each day for 4 consecutive days."

If we define y = number of propane stoves sold and x = number of days, then we can write this as:

y = 5*x

Where x goes from 0 to 4, so this can be represented with a linear equation.

"Cooper's profit decreases by $125 each day for 5 days."

Similar to before, we have a fixed change per day, so this again can be modeled with a linear equation.

"Cooper's profit doubles each month for 3 consecutive months."

This can not be modeled with a linear equation, the problem here is that the change is not fixed.

Because the profit is doubled, the change will depend on the value of the profit (so the double of 4 is not the same as the double of 5, just to give an example). Thus, this can not be modeled with a linear equation, this actually needs an exponential equation.

"Cooper sells 2 fewer fishing poles each day for 1 week."

Similar to the first and second case, each day he has 2 fewer fishing poles, a fixed number per day, thus, this can be modeled with a linear equation.

tickets at a particular movie theatre have different rates for adults and children. on a friday the theatre sold 4 adult tickets
maria [59]
Using elimination method. Using substitution will cause some fraction problems.

c- child tickets
a- adult tickets

4a + 7c = $83
5a + 6c = $90

multiply by -5

-20a - 35c = -$415
20a + 24c = $360

-11c= -$55
c = $5 child tickets

4a + 7(5)= $83

4a + 35 = $83

4a = $48

a= $12 adult tickets

How can Kendra determine if the function is actually linear?
pashok25 [27]

Answer:

D. She can check to see if the rate of change between the first two ordered pairs is the same as the rate of change between the first and last ordered pairs.

Step-by-step explanation:

Find the rate of change between first two ordered pairs and the second two ordered pairs:

1. Points (2,4) and (3,9). Rate of change:

\dfrac{y_2-y_1}{x_2-x_1}=\dfrac{9-4}{3-2}=\dfrac{5}{1}=5

2. Points (3,9) and (4,16). Rate of change:

\dfrac{y_2-y_1}{x_2-x_1}=\dfrac{16-9}{4-3}=\dfrac{7}{1}=7

The rate of change for the linear function must the same for each two points on the graph of the function. In this case, the reate of change differs, so this function is not linear and correct option is D.

A jar holds 128 fluid ounces of juice. The label says the jar has 16 servings. How many fluid ounces are needed for 80 servings?
Bumek [7]
There are 16 servings for each 128 fluid ounces of juice. 

Divide 80 servings by 16 servings, and 5 should be the quotient. Therefore, there are 5 jars of juice. Multiply 128 by 5 since 128 fluid ounces are in one jar. The answer should be 640 fluid ounces.
