Answer:

$36(x-25y)$

Step-by-step explanation:

Bring out the common factor of 4 from the equation

$4(9x-225y)$

9 and 225 share a common factor of 9. Factor the 9 out

$9 \times 4 (x-25y)$

$36(x-25y)$

the midpoint of kl is m(4.8, -7.8). one endpoint is l(0.6, -5.6). find the coordinates of the other endpoint k.

Vera_Pavlovna [14]

$\bf ~~~~~~~~~~~~\textit{middle point of 2 points }\\\\
\begin{array}{ccccccccc}
&&x_1&&y_1&&x_2&&y_2\\
% (a,b)
&k&(~ x &,& y~) 
% (c,d)
&l&(~ 0.6 &,& -5.6~)
\end{array}\qquad
% coordinates of midpoint 
\left(\cfrac{ x_2 + x_1}{2}\quad ,\quad \cfrac{ y_2 + y_1}{2} \right)$

$\bf \left( \cfrac{0.6+x}{2}~~,~~\cfrac{-5.6+y}{2} \right)~=~\stackrel{midpoint}{(4.8~,~-7.8)}\quad 
\begin{cases}
\cfrac{0.6+x}{2}=4.8\\\\
0.6+x=9.6\\
\boxed{x=9}\\
---------\\
\cfrac{-5.6+y}{2}=-7.8\\\\
-5.6+y=-15.6\\
\boxed{y=10}
\end{cases}$

Use an inverse matrix to solve for the system of equations.

IrinaK [193]

Answer:

(-1, 7, 2)

Step-by-step explanation:

we suppose that ax + by + cz = d for the matrix

D = det [ 0 4 7] = 100

-6 0 -2

1 2 8

Dx= det [ 14 4 7] = - 100

10 0 -2

-3 2 8

Dy= det [ 0 14 7] = 700

-6 10 -2

1 -3 8

Dz = det [ 0 4 14] = 200

-6 0 10

1 2 -3

So the solution is:

x = Dx/D = -1, y = Dy/D= 7, z =Dz/D = 2

(-1, 7, 2)

have a good day!
