1. tickets to a concert were $5 for children and $10 for adults. if attendance at one show was 800, and the total receipts for that show were $7000, how many adults attended?

The number of adults attended was 600

Step-by-step explanation:

Let

x ----> the number of children attended

y ----> the number of adults attended

we know that

-----> equation A

----> equation B

Solve the system by graphing

The solution of the system of equations is the intersection point both graphs

using a graphing tool

The solution is the point (200,600)

see the attached figure

therefore

The number of children attended was 200 and the number of adults attended was 600

horizontal translation of 2 units in the positive x direction

followed by

vertical translation of 3 units in the positive y direction

to plot points   for x just start at the origin (middle) and go to the left however many times it say(if the number is a positive) if the number is a negative then go right however many times it says if it is 0 go nowhere

now keep you pencil there and go up however many times it says on y(if it is positive) if it is negative then go down however many times it says. if it says 0 go nowhere.

you have just plotted a point! now when you finish plotting all of them connect them with a ruler

plot each point as (-3, 7), (0,4), (3,1), (8,-4)   in the parenthesis on the left of the comma is x and the right is y.
