Click to show whether each equation represents a linear or nonlinear function.

Answers

Answer:

[tex]y = x^2 + 1[/tex] -- Nonlinear

[tex]y = x^1 + 2[/tex] -- Linear

[tex]y = x[/tex] --- Linear

[tex]y = 5(x + 2)[/tex] --- Linear

[tex]y = x(x)[/tex] --- Nonlinear

Step-by-step explanation:

Required

Categorize each function as linear or nonlinear

First, it should be noted that a linear function has the form [tex]y = mx + b[/tex].

So, the following question will be solved based on the above form

(a):

[tex]y = x^2 + 1[/tex]

This can not be expressed as [tex]y = mx + b[/tex]

Hence, it is a nonlinear function

(b):

[tex]y = x^1 + 2[/tex]

This can be further expressed as:

[tex]y = x + 2[/tex]

This has the same form as [tex]y = mx + b[/tex].

Hence, it is a linear function.

(c):

[tex]y = x[/tex]

This can be further expressed as:

[tex]y = x + 0[/tex]

This has the same form as [tex]y = mx + b[/tex].

Hence, it is a linear function.

(d):

[tex]y = 5(x + 2)[/tex]

This can be further expressed as:

[tex]y = 5x + 10[/tex] -- by opening the bracket

This has the same form as [tex]y = mx + b[/tex].

Hence, it is a linear function.

(e):

[tex]y = x(x)[/tex]

This can be further expressed as:

[tex]y = x^2[/tex] --- by opening the bracket

This can not be expressed as [tex]y = mx + b[/tex]

Hence, it is a nonlinear function

A pan has an original price of $32 but is marked down by 15 percent. Which equation shows the new price of the pan? (32 dollars) (100 percent minus 15 percent) = (32 dollars) (85 percent) = 27 dollars and 20 cents
(32 dollars) (15 percent) = 4 dollars and 80 cents
(32 dollars) (15 percent) + 32 dollars = 4 dollars and 80 cents + 32 dollars = 36 dollars and 80 cents
(32 dollars) (185 percent) = 59 dollars and 20 cents

Answers

Answer:Its A) ($32) (100%-15%) = ($32) (85%) = 27.20

Amelia needs to buy some cat food. At the nearest​ store, 6 bags of cat food cost ​$22.50. How much would Amelia spend on 3 bags of cat ​food?

Answers

It would be 11.25. Basically you are getting half of the amount so the cost would be half.

Answer:

11.25 I would think

Step-by-step explanation:

3 is half of 6, so you basically just divide by 2. 22.50/2=11.25

what is 4/5 plus 2/3

Answers

Answer:

1 [tex]\frac{7}{15}[/tex]  or

[tex]\frac{22}{15}[/tex]

Step-by-step explanation:

Answer:

22/15 or 1 7/15

Step-by-step explanation:

4/5 + 2/3

So first you have to change the denominator to the same digit by finding a number they both go in to so:

12/15 and 10/15

then add them together and you'll get: 22/15

simplified it'll be 1 7/15

Wilbur was training for a race that was 6 1/4 miles long. He could only run 1 1/4 miles before needing to stop to take a break. How many times will Wilbur need to take a break during his run?

Please help

Answers

Answer:7 2/4

Step-by-step explanation:

Alright let’s go step by step for this:

1.) 6 1/4 - 1 1/4 = 5

2.) If he can run 1 1/4 miles before needing a break you would have to divide that number into the subtracted number from above

5 ÷ 1 1/4

3.) simplify the equation

5 ÷ 1.25

4.) Then divide

5 ÷ 1.25 = 4
