1: (-1,-1) is (x, y) to see if it is a solution, you would just plug in x and y and see if the equation is true.
-4 (-1) + 2(-1) = 2
4 + -2 = 2
2 = 2 CORRECT
So... plug in x and y in the second equation to Make sure it works for that one too.
-1 + -1 = -2
-2 = -2 CORRECT
So, yes. (-1,-1) is a solution to both equations.
Step-by-step explanation:

So this statement is caused for subtracting. So we have to subtract 6,700.00 from 3,995.00 and the answer would be 2705
Hope this helps :)
2+2=4
a^2+b^2=c^2
15^2-4^2
=225-16
=209
Answer:
Current water in dam = 1,676.202 million m³ (Approx.)
Step-by-step explanation:
Given:
Storage capacity of dam = 2,536 million m³
Current water level = 65.4%
Find:
Current water in dam
Computation:
Current water in dam = Storage capacity of dam x Current water level
Current water in dam = 2,563 x 65.4%
Current water in dam = 1,676.202 million m³ (Approx.)
