Answer:
-4y^2+2y+3
Step-by-step explanation:
(2y+1)-4y^2+2
2y+1-4y^2+2
-4y^2+2y+1+2
-4y^2+2y+3
The equation would be:
m = 30b where 'm' represents the amount of money and 'b' represents the number of boxes sold.
m is the dependent variable
b is the independent variable
Negative correlation between two variables means when x is increasing but y is decreasing or vice versa.
First graph of suffered animals and children shows a positive slope which means if age of child increasing then numbers of suffered animal is also increasing.So, the first graph show a positive correclation.
Second graph of survey of adults doesn't represnt any distinct relationship as the data scattered randomly everywhere in the graph. So, it's showsa very week correlation.
Third graph of speed and MPG shows a negative slope as speed is increasing then MPG is decreasing. So, the third graph (speed and MPG) shows a negative correlation.
Answer
-8 
r > 0
Step-by-step explanation:
you know that r is less than or equal to -8, so you write that, and then you know that r is also greater than 0, so then you add that to it, and then you have the answer. r will be in the middle because it is the range of what are can be.
