Answer:
I don't know sorry for no answer
(2x - y = -2)2
5x - 2y = -7
4x - 2y = -4
Subtract both
x = -3
5(-3) - 2y = -7
-15 - 2y = -7
-2y = 8, y = -4
Solution: (-3,-4)
Answer:
50%
Step-by-step explanation:
The chances of getting either heads or tails on a coin is 50/50. Convert that to probability and that is 1/2. Convert it to percentage of 100 and it is 50%.
Only time a coin isn't 50/50 is if the coin itself is a weighted coin.

Step-by-step explanation:
Answer:
(f-g)(x)
= -x^2 - 2x + 2
Step-by-step explanation:
(f-g)(x) means
f(x) - g(x)
= x - 2 - (x^2+3x-4)
distribute the subtraction to all three of the last terms.
= x - 2 - x^2 - 3x + 4
combine like terms
= -x^2 - 2x + 2
