Can someone explain how to solve this?

Answer:

(-8,8)

Step-by-step explanation:

Simplify |n| + 4 < 12. To do this, subtract 4 from both sides. This results in:

|n| < 8. The solution set includes all real numbers between -8 and 8, but not -8 itself or 8 itself.

Line segment DB and line segment AE are medians. If BC=6y+10, AB=22+3y, CE=6x+12, ED=2x+60, then find the value of x and y, and

garri49 [273]

Answer:

$x=45.5,\ y=\dfrac{280}{3}.$

Step-by-step explanation:

Line segment DB and line segment AE are medians, then

$AD=DC=\dfrac{1}{2}AC;$
$BE=CE=\dfrac{1}{2}BC.$ .

This gives you that $6x+12=\dfrac{6y+10}{2}.$

By the triangle midline theorem,

$DE=\dfrac{1}{2}BC,$

then

$2x+60=\dfrac{22+3y}{2}.$

Solve the system of two equations:

$\left\{\begin{array}{l}6x+12=\dfrac{6y+10}{2}\\ \\2x+60=\dfrac{22+3y}{2}\end{array}\right.\Rightarrow \left\{\begin{array}{l}12x+24=6y+10\\ \\4x+120=22+3y\end{array}\right.\Rightarrow \left\{\begin{array}{l}6x-3y+7=0\\ \\4x-3y+98=0\end{array}\right.$
