Answer:
x < 1 and x > -19
Step-by-step explanation:
(4 |x+9|)/5<8
4 |x+9| < 40
|x+9| < 40/4
|x+9| < 10
x + 9 < 10. x < 1. (Positive answer: <)
x + 9 > - 10. x > - 19 (negative answer: >)
Five exterior angles of a hexagon are 41° 32°,67º 71°, and 55°, What is the measure of the sixth exterior
Let d = discriminant
d = b^2 - 4ac
Let a = 2, b = 4 and c = -9
We now plug and chug.
d = (4)^2 - 4(2)(-9)
d = 16 - 8(-9)
d = 16 + 72
d = 88
