Simplify.<br> (WILL GIVE BRAINLIEST)
Novosadov [1.4K]

Answer:

\frac{\sqrt{x} }{2x}

Step-by-step explanation:

Rationalize the denominator first (keep in mind we are NOT solving this because there is no equals sign here.  We are merely simplifying.)

\frac{\sqrt{5x} }{x\sqrt{20} } *\frac{\sqrt{20} }{\sqrt{20} } =\frac{\sqrt{100x} }{20x}

Now simplify by taking the square root of 100 to get:

\frac{10\sqrt{x} }{20x}

Divide numerator and denomiator by 10 to get:

\frac{\sqrt{x} }{2x}

HURRY!!! I WILL GIVE BRAINLIEST FOR CORRECT ANSWER
Sergeeva-Olga [200]

Answer:

A function is a relation in which each element of the domain, or x-value, is mapped to one element of the range, or y-value.

The question we are asked is if cost is a function of the activity type.  This means that cost would be the range and activity type would be the domain.

If this is a function, then each activity type would have only one cost.  However, on different days of the week each activity type has different prices; this means there is more than one cost for each activity type, and it is not a function.
