Student Council is selling tickets to the Winter Dance. Tickets cost $5 per person
or $8 per couple. To cover expenses, at
least $1200 worth of tickets must be sold.
No more than 500 students can fit in the
gym where the dance is being held.

Let x = number of single tickets sold
3
Let y = number of couples tickets sold
X X X
In rows 5 and 6, write two different
inequalities to represent this situation. (one
for cost, and one for number of tickets)

the slope of the line is 60

one point on the line is (40,10)

step-by-step explanation:

in the equation outside the parenthesis the equation always tells you the slope. in this case it is 60.

in the parenthesis is also says 40 which is x because it is near the x and 10 is y because it is near y.

correct choice is b

step-by-step explanation:

when you calculate the average rate of change of a function, you are finding the slope of the secant line between the two points. for the function the average rate of change from point to point can be calculated as

to find the average rate of change from day 2 to day 10, note that at day 2, 8 houses were sold, so a(2,8) and at day 10, 2 houses were sold, so b(10,2). thus,
