What is the answer for -2x = 34

Mathematics

Alinara [238K]3 years ago

Hello!

Answer:

\boxed{X=-17}

<u><em>*The answer must have a NEGATIVE sign!*</em></u>

Step-by-step explanation:

First, you divide by -2 from both sides of an equation.

\frac{-2x}{-2}=\frac{34}{-2}

Then, you divide by the numbers from left to right.

34/-2=-17

\boxed{X=-17}, which is our the correct answer.

Hope this helps!

Have a nice day! :)

:D

-Charlie

Thank you!

To solve:

-2x = 34
----- -----
-2 -2

(-2x means -2 times x, so to undo this we need to divide by -2 on both sides)

x = -17

Then you do basic division (knowing that a positive divided by a negative results in a negative answer). And that's it!

The length of a rectangle is 2/5 its width and the perimeter is 280 inches, what are the length and width of the rectangle?
bogdanovich [222]
If the length is 2/5, or .40, then:

280/.40= 700

Check my answer:

.40*700= 280

The length is .40 (or 2/5) the width is 700.

I hope this helped!

What is an equation of the line that passes through the points (-2, 1) and (-8, 4)?
goldenfox [79]
<h2>Answer:   y =  - ¹/₂ x    OR  y - 1 = - ¹/₂ (x + 2)   </h2>

<h3>Step-by-step explanation:  </h3>

        For us to write the equation for this line, we need to (1) find the slope of the line, and (2) use one of the points to write an equation:  

       The question gives us two points, (-2, 1) and (-8, 4), from which we can find the slope and later the equation of the line.

<u>Finding the Slope  </u>

The slope of the line (m) = (y₂ - y₁) ÷ (x₂ - x₁)    

                                         =  (4 - 1) ÷ (-8 - (-2))  

                                         =   - ¹/₂  

<u>Finding the Equation</u>  

We can now use the point-slope form (y - y₁) = m(x - x₁)) to write the equation for this line:

                                 ⇒  y - 1 =   - ¹/₂ (x - (-2))

                                  ∴  y - 1 = - ¹/₂ (x + 2)

  we could also transform this into the slope-intercept form ( y = mx + c)  

                                   since  y - 1 = - ¹/₂ (x + 2)

                                           ⇒     y =  - ¹/₂ x

Write an equation in slope-intercept form of the line that passes through (6,-2) and (12,1)
yarga [219]

Equation in slope-intercept form of the line that passes through (6,-2) and (12,1) is:

y =\frac{1}{2}x-5

Step-by-step explanation:

Given points are:

(x1,y1) = (6,-2)

(x2,y2) = (12,1)

The slope intercept form is:

y=mx+b

We have to find the slope first

m =\frac{y_2-y_1}{x_2-x_1}\\=\frac{1-(-2)}{12-6}\\= \frac{1+2}{6}\\=\frac{3}{6}\\=\frac{1}{2}

Putting the value of slope

y = \frac{1}{2}x+b

To find the value of b, putting (12,1) in the equation

1 = \frac{1}{2}(12)+b\\1 = 6+b\\b = 1-6\\b=-5

Putting the values of m and b

y =\frac{1}{2}x-5

Hence,

Equation in slope-intercept form of the line that passes through (6,-2) and (12,1) is:

y =\frac{1}{2}x-5
