Answer:
The value of x = -13
Step-by-step explanation:
Given the expression
Multiply both sides by 2
simplify
Subtract 1 from both sides
Simplify
Divide both sides by 0.2
Simplify
Therefore, the value of x = -13
When taking square roots, you can't take square roots of negative roots of negative numbers. So, what will work for the domain of u(x) is what makes u(x) zero or more. We can make an inequality for that.
u(x) ≥ 0.
9x + 27 ≥ 0 by squaring both sides
9x ≥ -27
x ≥ -3
So the domain of the function is when x ≥ -3 is true.
