9 -4n+ 3n = 8n + 3 -3

Mathematics
1 answer:

3 0

Answer:

Answer:

n = 1

Step-by-step explanation:

This equation is just basic alegebra.  First, combine like terms to get

9 - n = 8n.  (Because 3 - 3 = 0, and -4n + 3n = -n.)  Now the equation is much simpiler;  add n to both sides to get 9 = 9n.  Divide 9 by both sides to get that n = 1.  

You can check your answer by plugging 1 in for n.  

9 - 4(1) + 3(1) = 8(1) + 3 - 3

9 - 4 + 3 = 8 + 3 - 3

5 + 3 = 11 - 3

8 = 8

Therefore, n is proven to equal 1.  

Hope this is helpful kid sorry i went very far yesterday hope you can forgive me but Anyways here it is <3

Find the equation of the line that passes through the points (-4,-2) and (-3,5) in both point-slope form and
kaheart [24]
<h2>Answer:</h2>

First, we must determine the slope, then we find the y-intercept using slope formula and slope-intercept form.

<u>For slope:</u>

<u />m = \frac{5 + 2}{-3 + 4} = \frac{7}{1} = 7<u />

Slope (m) = 7

<u>For y-intercept:</u>

<u />5 = 7(-3) + b\\\\5 = -21 + b\\\\26 = b<u />

Y-intercept (b) = 26

Using this information, we can now create the equations for this line.

y= 7x + 26\\\\y - 5 = 7(x + 3)

Formulas:

Slope formula: <em>y₂ - y₁/x₂ - x₁</em>

Slope-intercept form: <em>y = mx + b</em>

Point-slope form: <em>y - y₁ = m(x - x₁)</em>

<em></em>

*Note: (x₁, y₁), (x₂, y₂) = <em>2 points on the line</em>

50 (x+ 10) = 240<br> Whats the value for x
Katen [24]

Answer:

-26/5 or -5.2

Step-by-step explanation:

First, you need to expand the parentheses:

50x+500=240

Now, subtract 500 from both sides:

50x=-260

Now, divide both sides by 50

x=-26/5=-5.2

Hope this helps!
