Brainliest will be appreciated thank you!
Answer:
A (-5,2)
Step-by-step explanation:
5x+y=-23
7x-3y=-41
3×(5x+y)=3×(-23)
15x+3y=-69
<u>+</u><u>7x-3y</u><u>=</u><u>-41</u>
<u>22x</u>=<u>-110</u>
22. 22
x=-5
5x+y=-23
5(-5)+y=-23
-25+y=-23
<u>+25</u><u>.</u> <u>+25</u>
y=2
When using elimination you add both equations together so that one variable cancels out the other. In this situation, y can be the variable. You must get the y-variables to cancel out leaving just the x- variables to solve for.
Well....
A prime number is a number that can be divided by 1 or by itself, also having to be a whole number greater than 1. Ex. 5 can be divided by 1 or 5 so it is prime.
Hope this helps!
Recall that

So we have

So either
.
Since
, we expect
, so we take the negative square root. Then

This then means we have
