Answer:
13
Step-by-step explanation:
Since -5 is less than zero, we use the second equation, and substitute the -5 in for the x.
-2(-5)+3=13
For number 2 problem:
10x=5y
15x=7.5y
20x=10y
For problem3:
3x=1.5y
4x=2y
5x=2.5y
16/9x+11/9= y
Just adding the numbers on the y side so they cancel out and leave y alone. Now to leave y without the number in front you simply divide.
- i =
- Product rule of radicals: √ab = √a x √b
Firstly, factor out i: 
Next, apply the product rule of radicals here as such:
<u>Your answer is 5i√2, or the second option.</u>
