6/x=5/y
=> 6*y=5*x
=> 6/5=x/y
Given equation is
To find the x coordinate of vertex we use formula
From the given equation a= 2, b= 8 and c= -5
Plug in all the values
The x coordinate of vertex is x=-2
To find y coordinate of vertex we plug in -2 for x in the given equation
So vertex is (-2,-13)
If set A shows the statistians and B shows the person who bath regularly then the notation which shows that all statistians bath regularly is A∩B.
Given that A shows the statistians and B shows the person who bath regularly.
We are required to show the sentence that "All statistians bath regularly"in set notation.
We know that set is a collection of things, place,anything which can be measured or denoted as something else.
"∪" shows union means when we put this sign between two sets then the resulting set will contain all the elements of both the sets.
"∩" shows intersection means when we put this sign between two sets then the resulting set will contain all the common elements of both the sets.
Since A represents statistians and B represents people who bath regularly and we require statistians who bath regularly is A∩B.
Hence if A shows the statistians and B shows the person who bath regularly then the notation which shows that all statistians bath regularly is A∩B.

Step-by-step explanation:
Answer: $300 per month (assumed)
Step-by-step explanation:
As figures are lacking in this question, I will use assumed figures and you can use it as a reference.
Assume Penelope had been tutoring for 60 hours a month and her hourly rate was $10 originally.
If she reduces this time to half, the amount of hours she begins to tutor is:
= 60 hours / 2
= 30 hours
At a rate of $10 an hour, her monthly income becomes:
= 10 * 30
= $300 per month
