Answer:
40
Step-by-step explanation:
b² - 4ac
= 16 - 4(3)(-2)
= 16 + 24

Answer:
A: -41/9
Step-by-step explanation:
Substitute the point (4, -5) and slope -1/9 into the equation y = mx + b.
-5 = -1/9(4) + b
-5 = -4/9 + b
Solve for b:
b = -41/9
Our equation: y = -1/9(x) - 41/9
4/5 = 8/10 = 12/15 = 16/20 = 20/25
