q=5q⋅<span>(18)
</span></span></span>Simplify the right side.
Multiply <span><span>5q</span></span> by <span>18</span> to get <span><span>5q<span>(18).
</span></span></span><span><span>q=5q<span>(18)
</span></span></span>Multiply <span>18</span> by <span>5</span> to get <span>90</span>.
<span><span>q=90q
</span></span>Move all terms containing <span>q</span> to the left side of the equation.
Since <span><span>90q</span></span> contains the variable to solve for, move it to the left side of the equation by subtracting <span><span>90q</span></span> from both sides.
<span><span>q−90q=0
</span></span>Subtract <span><span>90q</span></span> from <span>q</span> to get <span><span>-89q</span></span>.
<span><span>−89q=0
</span></span>Divide each term by <span><span>-89</span></span> and simplify.
Divide each term in <span><span>−89q=0</span></span> by <span><span>-89</span></span>.
Simplify the left side of the equation by cancelling the common factors.
<span><span>q= 0/<span><span>89
</span></span></span></span>Divide <span>0</span> by <span><span>−89</span></span> to get <span>0</span>.
<span>q=<span>0</span></span>

Answer:
The function is defined when x > 0
Step-by-step explanation:
Functions with radicals are only undefined when the value in the radical is negative, because the root of a negative number is imaginary.
We know the function is undefined when the denominator is equal to zero. is equal to zero when x=0.
We also know that functions with radicals are undefined when the value in the radicals are negative, because the root of a negative number is imaginary. . will always be positive, but
is negative when x < 0.
So the function is undefined when x = 0, and when x < 0.
Therefore it is defined when x > 0
