Answer:
f(x)=−5x−20
Step-by-step explanation:
It's decreasing 5 degrees every hour, which is represented by -5x
You also have to take away the 20 (-20) from where it started.
So, f(x)=−5x−20
Answer:
Step-by-step explanation:
Yes because it has a constant rate of change
Answer:
40 Tickets
80 Tickets
Step-by-step explanation:
To find how many tickets it will take to break even, we use the formula:

Our variables are:
Fixed Cost = $200
Sales Price = $10
Variable Cost = $5
Let's plug in our values into the formula.



So the class needs to sell a total of 40 Tickets to break even.
Since we know that it takes 40 tickets to break even a $200 Fixed cost. To make a profit of $200, we simply multiply the number of tickets sold by 2.
Number of tickets for $200 profit = 40 x 2
Number of tickets for $200 profit = 80 Tickets.
So the class needs to sell 80 Tickets to make a $200 Profit.
Its two squares, so you need to start by finding the perfect roots that go into 117. If you need more help after that just comment :)
Answer:
gradient = -10
y intercept = 1
Step-by-step explanation:
y = mx + b
y = -10x + 1
m = slope ; hence, slope = -10 in the eqn
y intercept = when x = 0
y = -10(0) + 1
y = 1
