9.) The relation can not be a function only if the domain is the same. If you plot the points on a graph and use the Vertical Line Test(VLT) you would see that none of the points would be on the same line. It doesn't matter if the range is the same
10.)On the graph your y-intercept would be 2 so that is where you plot your first point. In order to find the slope you need to go up three spaces and one space to the left this is also known as "rise over run". *Remember you always go up spaces for "rise over run" but if the slope is positive then you go to the right and if its negative you go to the left.
I hope this helps love! :)
I believe that the answer is 20. I am not entirely sure though.
Answer:
Around the 3 + 6:-

Answer:
The answer is 4/9
Step-by-step explanation:
Hi. Here's the work.
First turn everything into an improper fraction.
÷
=
÷ 
To divide fractions we multiply by the flipped version of the fraction, or the reciprocal.
÷
= 
Now we just multiply the fractions!
= 
The answer is therefore 4/9. Please mark brainliest if possible and i hope you get a good grade on your homework. ;)
Answer:
0.525 = 52.5% probability that the two are from different families.
Step-by-step explanation:
A probability is the number of desired outcomes divided by the number of total outcomes.
In this problem, the order in which the two participants are selected is not important, so we use the combinations formula to solve this question.
Combinations formula:
is the number of different combinations of x objects from a set of n elements, given by the following formula.

Desired outcomes:
1 from the Harfield family(from a set of 7).
1 from the McCoy family(from a set of 9). So

Total outcomes:
2 from a set of 16. So

Probability:

0.525 = 52.5% probability that the two are from different families.
