[Side]
Since, a line is said to be perpendicular to another line if the two lines intersect at a right angle.
⇒ 
[leg] [Given]
Reflexive property states that the value is equal to itself.
[Leg] [Reflexive property]
HL(Hypotenuse-leg) theorem states that any two right triangles that have a congruent hypotenuse and a corresponding congruent leg are the congruent triangles.
then, by HL theorem;
Proved!
Answer:
Below.
Step-by-step explanation:
So calculate.
-1/6x+3+1/3x+1=x+4.
Cancel equal terms.
-1/6x+4+1/3x=x+4
Multiply both sides -1/6x+1/3x=x
collect like terms.
-x+2x=6x
move the variable from right to left.
x=6x
collect like terms
x-6x=0
Divide both sides
-5x=0
x=0
The image below shows y = 5/3x - 9 being graphed.
Hope this helps! :)
