So,
For every 2 large notebooks Ann orders, she orders 1 small notebook.
This can be stated as a ratio: 2:1
Add up the units to find the value of each unit.
2 + 1 = 3
Divide 48 by 3 to get the unit value.
48/3 = 16
The unit value is 16.
The number of large notebooks Ann orders is 2(16):16
This is a 2:1 ratio.
Therefore, Ann ordered 32 large notebooks and 16 small notebooks.
A.) is your answer
this is because it is the only table with the pair of (0,0) This means it passes through the origin, and if it passes through the origin it is proportional, if it doesn't it isn't proportional
D.) is also your answer
This is because the equation of this line is y = 4x since there is no "B" this means it is proportional
Answer:

Step-by-step explanation:
Z^2−6z−27=0
Factor left side of equation.
(z+3)(z−9)=0
Set factors equal to 0.
z+3=0 or z−9=0
z=−3 or z=9
