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

This isn't really relating to sports homework or anything but rather math. Could the amount of yards lost in a football game be a fraction? Thank you.

Answers

Answer:

When writing a fraction there are two main parts: the numerator and the denominator. The numerator is how many parts you have. The denominator is how many parts the whole was divided into. Fractions are written with the numerator over the denominator and a line in between them.

So technically, Yes. How ever, I would need more information to give you an example.

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

Mai’s backpack weighs 9 pounds. Han’s backpack weighs 8.3 pounds. Priya’s backpack weighs 7.75 pounds, and Kiran’s backpack weighs 6.125 pounds. Select all the true statements.

Group of answer choices

Han’s backpack is 2.175 pounds heavier than Kiran’s.

Mai’s backpack is 2.25 pounds heavier than Priya’s.

Han’s backpack is 16.05 pounds heavier than Priya’s.

Kiran’s backpack and Han’s backpack together weigh 14.3125 pounds.

The backpacks weigh 31.175 pounds together.

Answers

Answer: Han’s backpack is 16.05 pounds heavier than Priya’s.

Step-by-step expl

The true statements are:

Han’s backpack is 2.175 pounds heavier than Kiran’s.

The backpacks weigh 31.175 pounds together.

Here, we have,

Let's evaluate each statement:

Han’s backpack is 2.175 pounds heavier than Kiran’s.

To check if this statement is true, we need to find the difference between the weights of Han's and Kiran's backpacks:

Han's backpack weight - Kiran's backpack weight = 8.3 - 6.125 = 2.175

The difference is indeed 2.175 pounds, so this statement is true.

Mai’s backpack is 2.25 pounds heavier than Priya’s.

Similarly, we find the difference between the weights of Mai's and Priya's backpacks:

Mai's backpack weight - Priya's backpack weight = 9 - 7.75 = 1.25

The difference is 1.25 pounds, not 2.25 pounds. Therefore, this statement is false.

Han’s backpack is 16.05 pounds heavier than Priya’s.

Again, we calculate the difference between Han's and Priya's backpack weights:

Han's backpack weight - Priya's backpack weight = 8.3 - 7.75 = 0.55

The difference is 0.55 pounds, not 16.05 pounds.

Thus, this statement is false.

Kiran’s backpack and Han’s backpack together weigh 14.3125 pounds.

To check this statement, we add the weights of Kiran's and Han's backpacks:

Kiran's backpack weight + Han's backpack weight = 6.125 + 8.3 = 14.425

The sum is 14.425 pounds, not 14.3125 pounds.

Hence, this statement is false.

The backpacks weigh 31.175 pounds together.

To verify this statement, we add the weights of all four backpacks:

Mai's backpack weight + Han's backpack weight + Priya's backpack weight + Kiran's backpack weight = 9 + 8.3 + 7.75 + 6.125 = 31.175

The sum is indeed 31.175 pounds, so this statement is true.

In conclusion, the true statements are:

Han’s backpack is 2.175 pounds heavier than Kiran’s.

The backpacks weigh 31.175 pounds together.
