Answer:
<em>(2, - 6, 3)</em><em> </em>
Step-by-step explanation:
2x - y - 3z = 1 ⇒ y = 2x - 3z - 1 .... <em>(1)</em>
4x + 3y + 2z = - 4 .... <em>(2)</em>
- 3x + 2y + 5z = - 3 .... <em>(3)</em>
(1) ---> (2) and (3)
4x + 3(2x - 3z - 1) + 2z = - 4 ⇔ 10x - 7z = - 1 ... <em>(4)</em>
- 3x + 2(2x - 3z - 1) + 5z = - 3 ⇔ x - z = - 1 ⇒ x = z - 1 ---> (4)
10(z - 1) - 7z = - 1 ⇒ <u><em>z = 3</em></u>
<u><em>x = 2</em></u>
2(2) - y - 3(3) = 1 ⇒ <u><em>y = - 6</em></u>
<em>(2, - 6, 3)</em>

Step-by-step explanation:
<u>Answer:</u>
The slope of a line perpendicular to the line whose equation is 4x+6y=108 is 
<u>Solution:</u>
Given, line equation is 4x + 6y = 108.
We have to find the slope of the line which is perpendicular to the given line equation.
We know that, <u><em>product of slopes of perpendicular lines equals to – 1</em></u>
So, now, let us find the slope of the given line equation.

Now,
slope of given line
slope of its perpendicular line = -1


Hence, the slope of the perpendicular line is
Answer:
28
Step-by-step explanation:
6x + 7y - 5
x = 2
y= 3
6(2) + 7(3) - 5
12 + 21 - 5
33 - 5
28
Hope this helps! Have a wonderful day.
None because 90 + 45 + 50 = 185 and triangles cannot exceed the measurement of 180°
Hope this helps
