I can only help you with the second one. It is a positive correlation because it is going upwards. Good luck with the first one!
Answer:
it depends in how many marbles there were in total add more details and then I'll give more help
Step-by-step explanation:
The function of the polynomial is (b) 
From the graph, we have the following highlights
- The graph crosses the x-axis at x = -1 and x = 3
- The graph touches the x-axis at x = -2
The above highlights mean that:
- The function has a multiplicity of 1 at x = -1 and x = 3
- The function has a multiplicity of 2 at x = -2
So, the function of the polynomial is:

Assume a = 1.
So, we have:

Multiply

Hence, the function of the polynomial is (b)

Answer: See below
Step-by-step explanation:
<u>Given:</u>
AB = CD and BC = DE
<u>To prove:</u>
AC = CE
Statements Reasons
- AB = CD Given
- AB + CB = CD + BC Addition property of equality
- AB + BC = CD + DE Given: BC = DE
- AC = CE By segment addition: AB + BC = AC and CD + DE = CE
Therefore, AC = CE has been proved
Answer:
m= 2/17
Step-by-step explanation:
do the formula x1 and y1 and x2 and y2
x1, y1 x2, y2
(-11,15) (23,19)
when subtracting you ALWAYS START WITH YOUR Ys
19-15= 4
now subtract your Xs
23- (-11)= 34
now your answer is 4/34
but that's not the last step you can simplify it and make it smaller,
they both go into 2 so know divide both of then numbers by 2
and you should get 2/17
your final answer should be 2/17
