We are given with two coordinates
(10, 7, 20) and
(5, 3, -2)
Which can be used to create a linear equation represented by vectors
<x, y, z> = <x0, y0, z0> + t<mx, my, mz>
We can get the slope by
<mx, my, mz> = <10, 7, 20> - <5, 3, -2> = <5, 4, 22>

 <x, y, z> = <x0, y0, z0> + t<5, 4, 22>
At z = 0, and using the coordinates of either of the two points, the coordinates o the shadow of the point can be determined.

What is the value of x?
NemiM [27]
Alternate interior angles are congruent.  Therefore, set the two angles equal to each other and solve for x. 

3x+4= 115
3x+4 -4 = 115 -4

3x =  111
x= 111/3---> 37. Therefore, x = 37.

If x<br>varies directly as y.<br>x=5 and y=10. find the<br>Value of a x when y=<br>3​
Serggg [28]

Answer:

x = 1.5 when y = 3

Step-by-step explanation:

You can put this in a ratio:

x    :    y

5    :   10

1.5  :    3

x is 1.5 when y is 3.

Factorize (3r-2p)^2 - (3d-2e)^2

Hi my lil bunny!

❀ _____.______❀_______._____ ❀

Since both terms are perfect squares, factor using the difference of squares formula, a^2 - b^2 = ( a+ b) ( a-b) where a = 3r - 2p and b = 3d - 2e

_____________________________

So the answer is :  ( 3r - 2p + 3d - 2e ) ( 3r - 2p - 3d - 2e)
