Answer:

x=-8/3

Step-by-step explanation:

<em>well first we move the like terms to one side</em>

3x=-2-6

<em>then we calculate the numbers</em>

3x=-8

<em>in order to make "x" alone we divide all of then by 3</em>

x=-8/3

Find the slope of (2,3) and (6,7)
Brut [27]
To find the slope, we must use the formula stated below.

Slope = Change in Y / Change in X = (Y1 - Y2) / (X1 - X2)

Since our coordinates are given as (X, Y), we must pick a coordinate to be #1, and the other coordinate will be #2.

I'll use the first coordinate as our #1.

(3 - 6) / (2 - 7) = (-3) / (-5) = 3/5 which is our answer

What is the volume of a hemisphere with a radius of 3 cm, rounded to the nearest tenth of a cubic centimeter?
Kaylis [27]

Formula: V = (2/3) π r 3.

Radius is 3cm.

So, now we can plug it in to solve for the volume.

V = (2/3) π 3^3

First, let's multiply 3^3.

3^3 = 27

Then, 27 x π = 84.82

After, multiply by 2/3.

84.82 x 2/3 = 56.55

Lastly, round 56.55 to the nearest tenth of a cubic centimeter.

56.55 = 56.6

Therefore the volume of a hemisphere with a radius of 3cm is 56.6cm^3.

23, 24 And 25 please. Thank you!
Vesna [10]

Step-by-step explanation:

23. area of rect,r = 11 x 3.5 = 38.5cmsq

area of tri, t = 6 x3.5/2 = 10.5 cmsq

area of shaded region, sr = r-t

=> sr = 38.5- 10.5 = 28.5cmsq

24. area of square, s = 10x10 = 100mmsq

area of circle, c = pi x 5^2 = 78.5mmsq

area of shaded region, sr = s - c

=> sr = 100- 78.5 = 22.5mmsq

25. area of circle, c = pi x 6^2 = 113.04insq

area of tri, t = 6x12/2 = 36insq

area of shaded region, sr = c - t

=> sr = 113.04 - 36 = 77.04insq
