3y+10x-54=0 5y-2x-34=0<br><br> x=<br><br> y=
Blababa [14]
<h3>Answer:</h3><h2>x = 3 and y = 8 → (3, 8)</h2><h3>Step-by-step explanation:</h3>

\left\{\begin{array}{ccc}3y+10x-54=0&\text{add 54 to both sides}\\5y-2x-34=0&\text{add 34 to both sides}\end{array}\right\\\left\{\begin{array}{ccc}3y+10x=54\\5y-2x=34&\text{multiply both sides by 5}\end{array}\right\\\underline{+\left\{\begin{array}{ccc}3y+10x=54\\25y-10x=170\end{array}\right}\ \ \ \ |\text{add both sides of the equations}\\.\ \ \ \ \ 28y=224\qquad\text{divide both sides by 28}\\.\ \ \ \ \ \ \ \dfrac{28y}{28}=\dfrac{224}{28}\\.\ \ \ \ \ \ \ \boxed{y=8}

\text{put the value of y to the first equation}\\\\3(8)+10x=54\\24+10x=54\qquad\text{subtract 24 from both sides}\\24-24+10x=54-24\\10x=30\qquad\text{divide both sides by 10}\\\dfrac{10x}{10}=\dfrac{30}{10}\\\boxed{x=3}

Can y’all help me with this please will give you the brainliest
polet [3.4K]

Answer and Step-by-step explanation:

A pair of segments that are perpendicular to each other are the line segments:

KI (the letter i) and MJ.

This is because we see that at the intersection T, there a right angle symbol, which means that those 4 angles at the intersection are 90 degrees. When a line meets another line, and it is perpendicular to that line, they form 90 degrees.

So, those line segments are perpendicular.
