Find the slope of the line that passes through the points (3, 6) and (5, 3).
Temka [501]
(3,6)    (5,3)
(x1,y1)(x2,y2)

The slope equation is: y2-y1
                                 ---------
                                  x2-x1

Replace with numbers: 3-6/5-3

Minus 3 and 6 is equal to -3

Minus 5-3 is 2 

So the fraction is -3/2 (no need to divide because you can't simplify it)

So the slope is -3/2

For the equation you have to replace the letters by 0's 

3×0-2y=6
Times 3 and 0
0-2y=6
Now you want to get the y alone, so minus 0 from both sides 
   0-2y=6
  -0      -0

-2y=6

Divide -2y from the 6

-2y=6
----  ---
  -2   -2

y=3 

The y intercept is 3 with the slope of -3/2

What is the volume of the following triangular prism?
Firdavs [7]

Answer:

Step-by-step explanation:

In order to calculate the volume of a triangular prism you need 2 things:

The triangles area and the prism's height.

Any prism's volume can be calculated by multiplying its base area with its height.

The Area of a triangle can be calculated in different ways.

The most used and "normal" way is:

(width * height) / 2

Another way is by using herons formula, which looks like this:

a, b, c = different sides of the triangle (length)

s = (a + b + c) / 2

a = \sqrt{s (s-a)(s-b)(s-c)}

When you have the prism's base area (b_{a}) you just have to multiply:

b_{a}*h=V

(V = volume)

If you have any questions, just ask them in the comments below.

Have a good day! (●'◡'●)

A rectangle has an area of 342 square meters. The width is 2 more than 4 time the length. Find the length and width, in meters o
Anna35 [415]

Answer:

  • length: 9 m
  • width: 38 m

Step-by-step explanation:

Let x represent the length of the rectangle. The the width is (4x+2) and the area is ...

  x(4x+2) = 342

  2x² +x - 171 = 0 . . . . . divide by 2, rearrange to standard form

  (2x +19)(x -9) = 0 . . . factor

  x = -19/2 or +9 . . . . . the length is the positive solution: 9

  (4x+2) = 4(9) +2 = 38 . . . . find the width from the length

The length of the rectangle is 9 meters. The width is 38 meters.
