Answer:
1367 people
Step-by-step explanation:
The wording "a rate proportional to the number" indicates the function is exponential. The growth factor is 1200/1000 = 1.2 in 7 days, so the exponential function can be written ...
i(t) = 1000(1.2^(t/7))
After 12 days, the number infected is modeled as ...
i(12) = 1000(1.2^(12/7)) ≈ 1367
About 1367 people are infected 12 days after discovery.
You can plug in the numbers to check.
Y - 2x > 17
(8) -2(-5) > 17
8 + 10 > 17
18 > 17
This is true so
Final answer:
Yes, (-5,8) is a solution
Answer:
y=10.75
Step-by-step explanation:
46 + 1) + y = 5(y - 1) +9
47+y=5y-5+9
47+y=5y+4
Collect like terms
47-4=5y-y
43=4y
Divide by 4
43/4=4y/4
43/4=y
y=10.75
