Y= -2x-1 is the asnwer i think
hope this helped
for x = -2 → y = |-2| = 2 → (-2; 2)
for x = 0 → y = |0| = 0 → (0; 0)
for x = 2 → y = |2| = 2 → (2; 2)
Answer: divide the 60 and the 4 and that's your answer
Step-by-step explanation:
Add the time to the start time:
8:30
1 hour: 9:30 am
2 hours: 10:30am
3 hours: 11:30am
4 hours: 12:30pm
5 hours: 1:30pm
Then 45 minutes makes the time 2:15pm
Answer: 2:15 pm
Although the number of new wildflowers is decreasing, the total number of flowers is increasing every year (assuming flowers aren't dying or otherwise being removed). Every year, 25% of the number of new flowers from the previous year are added.
The sigma notation would be:
∑ (from n=1 to ∞) 4800 * (1/4)ⁿ , where n is the year.
Remember that this notation should give us the sum of all new flowers from year 1 to infinite, and the values of new flowers for each year should match those given in the table for years 1, 2, and 3
This means the total number of flowers equals:
Year 1: 4800 * 1/4 = 1200 ]
+
Year 2: 4800 * (1/4)² = 300
+
Year 3: 4800 * (1/4)³ = 75
+
Year 4: 4800 * (1/4)⁴ = 18.75 = ~19 (we can't have a part of a flower)
+
Year 5: 4800 * (1/4)⁵ = 4.68 = ~ 5
+
Year 6: 4800 * (1/4)⁶ = 1.17 = ~1
And so on. As you can see, it in the years that follow the number of flowers added approaches zero. Thus, we can approximate the infinite sum of new flowers using just Years 1-6:
1200 + 300 + 75 + 19 + 5 + 1 = 1,600
