Solve the system of equations. If the system has no solution, say that it is inconsistent. Graph the lines of the system.

Romashka-Z-Leto [24]

Answer:

The solution to the system of the equations will be:

$x=3,\:y=1$

Step-by-step explanation:

Given the system of the equations

$x+y=4$

$x-y=2$

solving the system of the equations

$\begin{bmatrix}x+y=4\\ x-y=2\end{bmatrix}$

$x-y=2$

$-$

$\underline{x+y=4}$

$-2y=-2$

solving

$-2y=-2$

Divide both sides by -2

$\frac{-2y}{-2}=\frac{-2}{-2}$

$y=1$

$\mathrm{For\:}x+y=4\mathrm{\:plug\:in\:}y=1$

$x+1=4$

$x=3$

Therefore, the solution to the system of the equations will be:

$x=3,\:y=1$

A regular decagon has a side length of 4 centimeters long if the decagon is divided into 10 congruent triangles each has an appr

ratelena [41]

Area of decagon is given by:
Area=1/2(nsr)
where:
n=number of sides
s=side length
r=height
thus the area will be given by:
Area=1/2(10*4*6.2)
Area=124 cm^2

Xy + 3ey = 3e, find the value of y'' at the point where x = 0.

Katyanochek1 [597]

y might be 1 and I got that cuz 0y+3ey=3e and replace y with 1 and you get 0•1+3e•1=3e and to be honest it kinda looks like it makes sense
