 8x - 6y + 4z = -58
-8x -   y + 3z =  23
      -7y + 7z = -35
7 (z-y) = -35
z - y = -5
z = y - 5
4x - 3y + 2y - 10 = -29
6x + 2y - y + 5 = -16

4x -  y = -19
6x + y = -21

10x = -40

x = -4
y = 3
z = -2

Thank you very much.

If a paint can holds 2.5 litres, whats the radius of the can if it has a height of 20 cm?
Sloan [31]
Hello!

2.5 litres = 1,000 * 2.5 = 2,500 cubic cm

 

volume = π * radius2 * height

  2,500 = π * r2 * 20


2,500 / 20π = r^2


(Square Root of) 2,500 / 20π = r^2


6.307  <span>centimeters </span>= r (Radius)

 Hope this Helps! Have A Wonderful Day! :)

What are the coordinates of the point (2, −3) after a counterclockwise rotation of 90° about the origin?
Katen [24]

Answer:

(2,-3) changes to (3,2)

A is correct.

Step-by-step explanation:

Given: The point (2, −3) after a counterclockwise rotation of 90° about the origin.

R_{90\circ}(x,y)\rightarrow (-y,x)

Rotation is counterclockwise about origin.  

(x,y)\rightarrow (-y,x)

We are given coordinate

(2,-3)\rightarrow (3,2)

We can see in diagram also. Please see the attachment for rotation.

Hence, (2,-3) changes to (3,2)
