So, no

FIrst, we can do 9 and apply it to both x and -3

So, 9x-27-x+3

So, 8x-24

SO, yes

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

Answer:

x =77 degrees

Step-by-step explanation:

All the angles added up equal 180 degrees so:

2x + 26 = 180

Subtract 26 from both sides:

2x = 154

Divide both sides by 2:

x =77 degrees

Answer:

please mark brainliest

2x + 26 = 180

2x=180-26= 154

x=154/2

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

Find the missing right triangle side lengths in the models of the Pythagorean Theorem below

Answers

Answer: 24, 10, 26 and 4.6, 5, 6.7

Step-by-step explanation: for the first triangle the square with the area 576 has side lengths of 24 because 24 is the square root of 576, the square with the area 676 has a side length of 26 because 26 is the square root of 576, and we already know the side lengths of the third triangle are 10 for the second triange we know the side length of the square with the area 21 is about 4.6 because √21 ≈ 4.6 and the square with the area 25 the side length is 5 because √25 = 5 and the last square the side length is 6.7 because √46 ≈ 6.7

2x+3y = -1

Answers

Answer:

Step-by-step explanation:

basically here we wanna get y by itself

so

2x + 3y = -1

subtract 2x from both sides

3y = -2x -1

then to get y by itself we have to divide everything by 3

y = -2/3x - 1/3

this is your equation in slope intercept form

hope this helps <3

Answer: y= -2/3 x -1/3

Explanation:

3y= -2x-1 (subtract 2x from 3y and transfer it to the other side)

y= -2x/3 -1/3 (divide 3 on both sides to leave y alone)

Final Answer: y= -2/3 x -1/3 (y equals to negative two-third x minus one-third)
