Answer:

The number of tickets and cost have a proportional relationship.

Step-by-step explanation:

The points on the graph would be (2,36) , (5,90) , (9,162)

Graph the lines to see if the 'lines' are straight or not.

36/2 = 18

90/5 = 18

162/9 = 18

You can just this to check, as you can see, the rate of change stayed the same, so it is linear and proportional (straight line). Constant of proportionality means that between any 2 points on a line, they will have the same rate of change (aka. slope).

* * *

I don't want to confused anyone so I'll use this chance to explain the difference between linear and proportional.

In simple terms, proportional relationships has the y-intercept at 0. So proportional lines cross the origin (0,0) while linear lines just has to be a straight.

Hope I was able to help! Good Luck!

Peter is considering two cell phone plans. The first company charges $400 for the phone and $30 per month for the calling plan that Peter wants. The second company charges $125 for the same phone, but charges $55 per month for the calling plan that Peter wants. After how many months would the total cost of the two plans be the same?

Answers

Company #1 is 30m+400=?
Company #2 is 55m+125=?
M=months

Now plug in numbers for m until they have the same totals
M=10= equation would equal $700 and $675
M=11=equation would equal $730 And $730

So after 11 months they will be the same cost.

Answer:

A= 2/6   B=3/5   C=12/8

Step-by-step explanation:

every number is a fraction so take the #5 for example, 5= 5/1.then multiply by the given fraction. easy

For number one, a is 2/6 but can be simplified to 1/3 by dividing the denominator and numerator by 2. B is 3/5 and c is 12/8 but we have to turn that improper fraction into a mixed fraction so it becomes 1 4/8 which simplified is 1 1/2

A television screen has length 16 and 1/2 inches, width w inches (meaning the width is unknown), and area 462 sq inches. Select the equation that represent the relationships of the side lengths and the area of the television screen.

Answers

Answer:

Option B , C , D are correct

Solution:

Given that television screen has length , width w inches, and area 462 square inches

The television screen is generally of rectangular shape

The area of rectangle is given as:

Area = length x width

From given question,

width = w

area = 462 square inches

Substituting the values in above formula,

Therefore Option B is correct

We can rewrite the above equation and find value of w

Thus option C is correct

We can rewrite the above equation

Thus Option D is correct

Answers

Answer:

y = 0.005x + 20.

Step-by-step explanation:

First, we need to make the equation. We can use y = mx + b.

b is the y-intercept, and in this case, it is 20. Plug it in: y = mx + 20. Our first point on the graph is (0,20).

The slope is 0.005 (y = 0.005x + 20), which is too small to graph, if you look at the x-axis labels. But that's okay! Plug in a number for x that you know is on the x-axis, such as 2,000.

y = 0.005(2000) + 20 = 30

Remembering (x,y), we have our second point on the graph (2000, 30).

Let's look for one more.

y = 0.005(14000) + 20 = 90

Our third point on the graph is (14000, 90).

Now, lets look for those points on the graph and make our line.
