$\frac{\sqrt{4x+15} }{\sqrt{x} } =3$

Answer:

Step-by-step explanation:

Multiply both sides by x to get rid or the denominator: $\sqrt{4x+15}=3\sqrt{x}$

Get rid of the square root by squaring both sides: $\left(\sqrt{4x+15}\right)^2=\left(3\sqrt{x}\right)^2$ = 4x + 15 = 9x

Just solve for x.

So thi sis really simple since you have an equal sign so

(n/3)-(5n/6)=1/3
to subtract fractions, make the bottom number the same
n/3 times 2/2=2n/6
(2n/6)-(5n/6) or (2n-5n)/6 so
-3n/6=1/3
multiply both sides by 6
-3n=6/3=2
-3n=2
divide both sides by 3
-n=2/3
mmultiply boht by -1
n=-2/3
tada
n=-2/3

See below for the domain and the range of the functions.

<h3>How to determine the domain and the range?</h3>

As a general rule, all linear functions have a domain and a range of all set of real numbers i.e. (−∞, ∞)

The functions (2), (3), (4), (5) and (6) are linear functions.

So, their domain and range are (−∞,∞)

For function (1), we have:

f(x) = 3(3)^x - 1

The above is an exponential function.

The domain of an exponential function is all set of real numbers i.e. (−∞, ∞)
