If it’s blank and just a negative sign the answer should be -1
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.
Answer:
The answer is 120
Step-by-step explanation:
The answer would be B) x = 4.
1.5x + 6 - 3 = 4.5x - 9
1.5x + 3 = 4.5x - 9
3 = 4.5x - 9 - 1.5x
3 = 3x - 9
3 + 9 = 3x
12 = 3x
12/3 = x
4 = x
x = 4.
Answer:
The answer to your question is x = 64; y = 20
Step-by-step explanation:
Angles 2x + 2 and 130° are vertical angles so they measure the same.
2x + 2 = 130
- Solve for x
2x = 130 - 2
2x = 128
x = 128/2
x = 64
Angles 3y - 10 and 50° are vertical angles, so they measure the same.
3y - 10 = 50
3y = 50 + 10
3y = 60
y = 60/3
y = 20
