What is the value of "x" if -2(3x+2)>-8x+6

Mathematics
1 answer:
lukranit [14]3 years ago
3 0

Answer:

<h2>x > 5</h2>

Step-by-step explanation:

-2(3x+2) > -8x+6

Expand the terms

That's

- 6x - 4 > - 8x + 6

- 6x + 8x > 6 + 4

2x > 10

Divide both sides by 5

<h3>x > 5</h3>

Hope this helps you.

What is the equation, in point-slope form, of the line that has a slope of 6 and passes through the point (–1, –8)? a. y+8 = 6 (
Stolb23 [73]

Answer:

y + 8 = 6(x + 1)

Step-by-step explanation:

The equation of a line in point- slope form is

y - b = m(x - a)

where m is the slope and (a, b) a point on the line

here m = 6 and (a, b) = (- 1, - 8), hence

y - (- 8) = 6(x - (- 1)), that is

y + 8 = 6(x + 1)

Robert ran 3 1/3 mph for 3/4 of an hour. How far did he run?​
matrenka [14]

Answer:

2 ½ miles

Explanation:

mph = miles per hour, which means that if robert had run for the full 1 hour, he would have run 3 ⅓ miles.

however, since he only ran for ¾ of an hour, which is equal to 0.75, we can multiply the 3 ⅓ miles by 0.75 to get 2.5 or 2 ½ miles.

i hope this helps! :D

Please help! 30 points and crown! A diagonal of a cube measures StartRoot 750 EndRoot cm. The diagonal of a face measures StartR
rodikova [14]

Let length, width, and height be s.

Then diagonal of any face would be √( s² + s² ) = √( 2s² )

And we know that it measures  √( 500 ) so that's sufficient for us to figure out the length of an edge of the cube. We do not need to worry about the diagonal of the cube.

Now we have to solve √( 500 ) = √( 2s² )

Square both sides:

500 = 2s²

Divide both sides by 2:

250 = s²

Take the square root of both sides:

√(250) = s ≈ 15.8113883

Rounding to nearest tenth:

s ≈ 15.8

Final answer: 15.8

Hope this helps.

The solution system to 3y-2x=-9 and y=-2x+5
Alecsey [184]

Answer:

\boxed{(3,-1)}

Step-by-step explanation:

<em>Hey there!</em>

<em />

Well to find the solution the the given system,

3y - 2x = -9

y = -2x + 5

So to find x lets plug in -2x + 5 for y in 3y - 2x = -9.

3(-2x + 5) - 2x = -9

Distribute

-6x + 15 - 2x = -9

-8x + 15 = -9

-15 to both sides

-8x = -24

Divide -8 to both sides

<u>x = 3</u>

<u />

Now that we have x which is 3, we can plug in 3 for x in y = -2x + 5.

y = -2(3) + 5

y = -6 + 5

<u>y = -1</u>

<u><em /></u>

So the solution is (3,-1).

<em />

<em>Hope this helps :)</em>
