Answer:
(-5,1)
Step-by-step explanation:
Add it together
3x - 2x = x
y - y = 0
9 - 14 = -5
x = -5
Choose a random equation, doesn't matter.
3x + y = -14
3(-5) + y = -14
-15 + y = -14
y = -14 + 15
y = 1
2_10 i'm guessing means 2/10, so in percentage, it would be 20%
10xBx15+11xB is that what you are needing for the answer because you didn't really say what you where looking for.
The answer would be D.
a1 is 0.5 and r is -0.2.
