Consider the surface given by
Mazyrski [523]
This is just simple. For example you have a plane of the form x=a, then you just substitute x with a, and you'll get an equation with y and z only, hence you have a 2-d trace of the intersection. It is just similar for y=b and z=c.

(1) At z=1.5, 2x^2 + 5y^2 + 1.5^2 = 4 
    2x^2 + 5y^2 = 1.75
    Now you have an ellipse in the z=1.5 plane as your trace.

(2) At x=1, 2(1)^2 + 5y^2 + z^2 = 4
    5y^2 + z^2 = 2
    Now you have an ellipse in the x=1 plane as your trace.


(3) At z=0, 2x^2 + 5y^2 + (0)^2 = 4
    2x^2 + 5y^2 = 4
    Now you have an ellipse in the z=0 plane as your trace.

(4) At y=0, 2x^2 + 5(0)^2 + z^2 = 4
    2x^2 + z^2 = 4
    Now you have an ellipse in the y=0 plane as your trace.

Ten times a number is sixteen more than twice the number. find the number
SVEN [57.7K]
Hello, there!

<span>Ten times a number is sixteen more than twice the number. Find the number.


Answer: 2
-----------------------------------------------------------------------------------------------------

Explanation:

</span>
First, let's write the equation.

Ten times a number -- 10x

16 more  -- 10x - 16

Twice the number -- 2x

10x - 16 = 2x or 10x = 2x + 16

Let's use the first one: 10x - 16 = 2x

First, let's isolate the x to one side.

10x - 16 = 2x
-10x          -10x

-16 = -8x

Now, let's multiply each side by -1 to make them positive

-16 = -8x
*-1    *-1

16 = 8x

Finally, let's divide each side by 8

16 = 8x
----  ----
  8    8

Our answer is 2 = x

This means that the number is 2.


I hope I helped!
