The domain is x and the range is f(x)
Your answer should be 264.
Answer:
120
Step-by-step explanation:
First, you have to calculate the money that Seth would spent if he goes to 30 movies if his father gets the summer movie pass by adding up the cost of the pass plus the result of multiplying the cost per movie with the pass for the number of movies:
30+(3*30)=30+90=120
Second, you need to calculate the money that Seth would spent if he goes to 30 movies without the pass by multiplying the normal price per movie for the number of movies:
8*30=240
Third, you need to find the difference between both costs:
240-120=120
According to this, the answer is that if Seth plans to go to 30 movies this summer, he would save 120.
Given the number of contestant in each round:
X 1 2 3 4 5
F(x) 243 81 27 9 3
Rate of change can be calculated using y2-y1/x2-x1 formula. From
rounds 1 to 4 the rate of change are
-162, -54, -18. And the average of it is -78 and it
represents the average rate at which the number of contestants changed from the
first round to the fourth round.
Answer: 2
Step-by-step explanation:
If you multiply -4 by 2 you get -8, so -8 divided by -4 must be 2
