A square is always positive:
Answer:
(2,-3)
Step-by-step explanation:
I used substitution and rearranged the second equation to y=-2x+1. Then I replaced the y in the first equation with -2x+1. So, I got 3x-5(-2x+1)=21. When you solve that you get 13x=26 or x=2. Then you replace x with 2 in either equation and end up with y=-3.
Its one, you get radical esquared which means ln e which is one if i remember correctly
The best approximation is 10 because the two closest perfect squares to 110 is 100 and 121. the one that's closest to 110 though is 100. the square root of 100 is 10.
