Answer:
I also agree! It's 13.8ft :)
Hi! I am not quite sure about the answer, but maybe try an equation I learned: y=kx and y/x = x? Maybe try and subtract the fractions or cross equalize? I am happy to give ideas!
First use the point slope form
y-y1=m(x-x1)
plug in the ordered pair to the y1 and x1 so
y--3=m(x--8)
add the slope and make the double minus into a plus
y+3=34(x+8)
then you can distribute the 34
y+3=34x+272
then to get it to slope intercept you subtract 3 from both sides of the equation to make it y=mx+b so
y=34x+269

Ordered triple are (4,-2,1)</h2>
Step-by-step explanation:
We need to find ordered triple of 2x + 5y - 3z = -5 , 3x + 2y + 7z = 15 and 5x - 4y + 6z = 34
2x + 5y - 3z = -5 -------------------------eqn 1
3x + 2y + 7z = 15 -------------------------eqn 2
5x - 4y + 6z = 34 -------------------------eqn 3
eqn 1 + eqn 2
5x + 7y + 4z = 10 -------------------------eqn 4
eqn 4 - eqn 3
11y - 2z = -24 -------------------------eqn 5
eqn 1 x 3
6x + 15y - 9z = -15 -------------------------eqn 6
eqn 2 x 2
6x + 4y + 14z = 30 -------------------------eqn 7
eqn 7 - eqn 6
-11y + 23z = 45 -------------------------eqn 8
eqn 5 + eqn 8
21 z = 21
z = 1
Substituting in eqn 8
-11y + 23 x 1 = 45
-11 y = 22
y = -2
Substituting in eqn 1
2x + 5 x -2 - 3 x 1 = -5
2x = 8
x = 4
Ordered triple are (4,-2,1)
