Simple...
you have: x-3y=18
You want to convert it into slope-intercept form or y=mx+b form-->>>
x-3y=18
Isolate the variable-->>
x-3y=18
-x -x
-3y=-x+18
Now simply divide...
y=
Thus, your answer.
Answer: x= 1, 
Step-by-step explanation:
The quadratic equation is
and
So we just need to sub in the proper numbers from the equation given, in this case, it would result in
and
Once we get this we can either manually simplify or use a calculator, using a calculator would result in the answers
x= 1,

Answer:
diameter = 2.5 feet
Step-by-step explanation:
Circumference of a circle is given as C = πd
Circumference of the tree trunk = 7.85 ft
π = 3.14
Diameter of the tree trunk = d
Thus:
7.85 = 3.14*d
Divide both sides by 3.14
7.85/3.14 = 3.14*d/3.14
2.5 = d
d = 2.5 ft
