Answer:


<u>Group the Variable's</u>:
2 x - 5 + 7 y - 3 = 9 x - 1 - y -8
2x -9x + 7y +y = -1 -8 +5 + 3
-7x + 8y = -1
<u><em>From this find x and y</em></u>
<u>For X</u>
-7x + 8y = -1
-7x = -1 -8y
7x = 8y + 1
x = (8y +1)/7
<u>For Y</u>
-7x + 8y = -1
8y = -1 +7x
y = (7x -1)/8
A histogram would best represent the data.
Dot plot is a good way to show a certain trend. However, when it comes to the number of a item, in this case the number of students in a certain score range, a histogram will be the most intuitive and concise. Thus, a histogram best represent the data presented here.
Total friends = 3
fare = $ J
She also paid $5 tip
So there is J amount of money splitted into 3 friends.
That means you divide J/3 .
After Angela also pays additional tip of $5.
That means you also add 5.
So the expression for how much Angela pay in total is: J/3 + 5

(a) The relation is a function because each value of x maps onto only one value of y.
(b) Domain is
