Solve 15 = 1/3x
x = ?

Answers

Answer 1

Hey there!

The answer to your question is x = 45

To solve this, we want to get x with a coefficient of 1 by itself on one side of the equal sign, and right now it's coefficient is 1/3. We can get a coefficient of 1 by multiplying both sides of the equation by 3.

15(3) = 1/3x(3)

45 = x

Hope this helps and if you need any further help, I would be happy to!

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

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

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)
