a school is planning a field trip to a theme park. a ticket to the park costs $21. for a group of 50 or more, there is a 12% discount. the school saved $819 with the discount. how many tickets did the school buy?

With a 12% discount, 18.48 is the price per ticket (2.52 per ticket saved). In order to determine the amount of tickets, we divide the saved amount by the amount saved per ticket.

819/2.52 is 325.

There were 325 tickets purchsed.

the answer is y < -3 or   y > 3

-3y > 7 + 2

-3 y > 9

y < -3

see attached

step-by-step explanation:

given the function as;

write the equation replacing f(x) with y

form   and fill a table containing values of y with corresponding values of x

you can take a range for   values of x as -3≤x≤3

solving for x=-3

for x=-2

repeat the same procedure to get the values of y for the remaining ,x=-1 to x=3

plot the values of y against values   of x and obtain the following graph
