The answer simplified is:
a= —2x^2+7x+22
Answer:
C (-2,1)
Step-by-step explanation:
−2x − y = 3 (1)
−9x − y = 17 (2)
(1) y = -2x - 3
(2) y = -9x - 17
-2x - 3 = -9x - 17
7x = -14
x = -2
y = -2(-2) - 3
y = 4 - 3
y = 1
80% of the time it will be heads, because 40/50 it's heads, and if you times both by 2 you get 80/100 = 80%
