Help me out guys.
Answer:
8
Step-by-step explanation:
The condition for the discriminant b² - 4ac is
If b² - 4ac > 0 then roots are real, irrational and unequal
If b² - 4ac > 0 and a perfect square, roots are real, rational and unequal.
Thus
b² - 4ac = 8
Answer:
3) 8
Step-by-step explanation:
Real and unequal:
B² - 4AC > 0
Irrational: B²-4AC not a perfect square
Answer:

Answer:
Mason's and Eric's
Step-by-step explanation:
We are given that:
Olivia has 18 marbles ,Mason has 24 marbles,Nia has 63 marbles,and Eric has 75 marbles.
Each person packed their marbles in groups of 9.
We have to find who will have marbles left over.
Olivia has 18 marbles which can be packed as (9+9=18)
Mason has 24 marbles which can be packed as (9+9=18 and 6 will be left unpacked)
Nia has 63 marbles which can be packed as (9+9+9+9+9+9+9=63)
and Eric has 75 marbles which can be packed as (9+9+9+9+9+9+9+9=72 and 3 will be left unpacked)
Hence, Mason's and Eric's marbles are left unpacked
change (-6,3) into (6,3)?
Answer:
A reflexion across the y-axis
point (x , y) reflected across the y-axis is point (-x , y)
Answer:
Reflection
Step-by-step explanation:
From the coordinates, the x variable changes its sign without having to change its y variable. So translation is impossible here.
Rotation would also be impossible to achieve this since it the coordinates would switch.
