Answer:

3x-2 = -x+10

or, 3x+x=10+2

or, 4x=12

or, x=12/4

So, x=3

Answer: 3

Step-by-step explanation:

Step 1: Add x to both sides.

3x−2+x=−x+10+x

4x−2=10

Step 2: Add 2 to both sides.

4x−2+2=10+2

4x=12

Step 3: Divide both sides by 4.

4x

4

=

12

4

What is the equation of a line that passes through point R(3,7) and has a slope of 6?
djyliett [7]
The answer in slope intercept form is y = 6x-11

If you want the answer in standard form, then it would be 6x-y =11

notes:
* Slope intercept form is y = mx+b
* Standard form is Ax+By = C
=====================================

Explanation:

The given slope is m = 6
The line goes through (x,y) = (3,7)

Plug those three values into the equation below. Isolate b
y = mx+b
7 = 6*3+b
7 = 18+b
7-18 = 18+b-18 ... subtract 18 from both sides
-11 = b
b = -11

So because m = 6 and b = -11, this means y = mx+b turns into y = 6x-11

The answer in slope intercept form is y = 6x-11

To convert to standard form Ax+By = C, we just have to get all the x and y terms together on the same side. I'm going to move the y term to the right side and move the 11 to the left side

y = 6x-11
y+11 = 6x-11+11
y+11 = 6x
y+11-y = 6x-y
11 = 6x-y
6x-y = 11

The answer in standard form is 
6x-y = 11
which is a different way to write the same line

How much water can this container hold
harina [27]

Answer:

972π cm³

Step-by-step explanation:

Okay so this container is a sphere, so you're going to want to use the volume of a sphere equation V = (4/3) * π * r³. In this case, you've got the diameter (d = 18), so divide by 2 to get r = 9.

So now you have all the variables you need to solve. Substituting those values into the volume equation, you get:

V = (4/3) * π * 9³ = 972π cm³.

ANSWER RIGHT FOR BRAINLIEST PLEASE equation of the line that passes through the point (–2, 3) and has a slope of 1/3
morpeh [17]

Answer:

y = \frac{1}{3} x + \frac{11}{3}

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Here m = \frac{1}{3}, thus

y = \frac{1}{3} x + c ← is the partial equation

To find c substitute (- 2, 3) into the partial equation

3 = - \frac{2}{3} + c ⇒ c = 3 + \frac{2}{3} = \frac{11}{3}

y = \frac{1}{3} x + \frac{11}{3} ← equation of line

B is the midpoint ofAC, AB = 4x – 2,<br> BC = 2x + 4. Find the lengths of AB,BC and AC.
