x=25
Step-by-step explanation:
2000=400√x
Step 1: Flip the equation.
400√x=2000
Step 2: Divide both sides by 400.
400√x/400=2000/400
√x=5
Step 3: Solve Square Root.
√x=5
x=52(Square both sides)
x=25

Answer: c= 49/4
Step-by-step explanation:
There are no pictures or tables
Slope of the line = (0- -5) / 6-3) = 5/3
in point slope form the equation is
y - 0 = 5/3( x - 6)
y = 5/3x - 10
multiply through by 3:-
3y = 5x - 30
In Standard form this is
5x - 3y = 30 Answer
