Solve the equation. Identify any extraneous solutions.

Mathematics
1 answer:
vovangra [49]3 years ago
3 0

Answer:

It's the second option:

0 and 3 are both solutions.

Step-by-step explanation:

h = √(3h)        Square both sides:

h^2 = 3h

h^2 - 3h = 0

h(h - 3) = 0

h = 0, 3.

If we plug h = 0 into the original equation:

0 = √(3*0) = 0 so this is a root.

x = 3:

3 = √(3*3) = 3 so this is also a root.

Which of these equations represent functions where x is the input and y is the output? Select each correct answer.
Andru [333]
The first equation is a constant.  There is no input necessary, and the output remains 5.
The second equation is also a constant.  The output is 4.
In the third equation, y depends on what value of x you use.  x is the input and y is the output.
In the fourth equation, x depends on what value of y you use.  The way it is written, y is the input and x is the output.
In the last equation, either x or y could be the input.  The other variable would change depending on which variable you replace with a number.
