For a non removable discontinuity, you want your function to equal some number (not zero) divided by zero when you plug in 3 for x

I can see that you’ve written and erased
1/(x-3)

This works as an answer. It would create a vertical asymptote, which is nonremovable

A customer has $10 to spend at the concession stand. Hotdogs cost $2 each and drinks cost $2.50 each. Graph the inequality that illustrates this situation. Use the space below to explain what the answer means.

Answers

Answer:

Please refer to the graph in the attached area.

Step-by-step explanation:

Given:

Total money available with the customer is $10.

Cost of each hotdog is $2.

Cost of each drink is is $2.50.

To find:

The graph of inequality.

Solution:

Let number of hotdogs bought = x

Total cost of hotdogs = 2x

Let number of drinks bought = y

Total cost of drinks = 2.5y

Total cost = 2x+2.5y

And total money available is $10.

So, the total cost calculated above must be lesser than or equal to $10.

Hence, the inequality is:

2x+2.5y<10

Also there will be two conditions on variables x and y:

x\ge0\ny\ge0

To graph this, let us find the points on the equivalent equation:

2x+2.5y = 10

Finding two points on the equation.

First put x = 0 \Rightarrow y = 4    

Then put y = 0, \Rightarrow x = 5

So, two points are (0, 4) and (5, 0).

Now, plotting the line.

Having point (1,2) in the inequality:

2 + 5 < 10 (True) hence, the graph of inequality will contain the point (1,2)

Please refer to the graph of inequality in the attached graph.

Richard is buying a subscription for video game rentals. The plan he has chosen has aninitial fee of $20 plus $2 per video game rented. This plan can be represented by the
function f(x) = 2x + 20. How much money will Richard pay this month if he rents 5 video
games?​

Answers

Answer:

Richard will pay $30.

Step-by-step explanation:

Because "x" is equivalent to the amount of video games he rents, you would replace "x" with 5. Do the math, and you would get 10+20=30! Hope this helps!
he will pay $30 this month
