<h3>
Therefore they are perpendicular.</h3>
Step-by-step explanation:
A equation of line is
y =mx +c
Here the slope of the line is m.
Given equations are
x - 2y = 18
⇔-2y = -x +18
............(1)
and 2x + y = 6
⇔y = -2x +6 ............(2)
Therefore the slope of equation (1) is
= 
Therefore the slope of equation (2) is
= -2
If two lines are perpendicular, when we multiply their slope we get -1.
therefore,
=
. (-2) = -1
Therefore they are perpendicular.

Step-by-step explanation:763
It already is a decimal unless you mean a repeating decimal, it would be .26 with a line over the number.
Answer:
<h2>x = 6</h2>
Step-by-step explanation:

Multiply through by 2
That's

<u>Expand</u>
That's
5x + 4 + 4x = 58
9x = 58 - 4
9x = 54
Divide both sides by 9
That's

We have the final answer as
<h3>x = 6</h3>
