The answer is B.)
This is because Since there is one value of y
for every value of x in (-1,-3),(3,-7),(7,-11),(9,-13)
, this <u>relation</u> is a <u>function</u>.

Answer:
Step-by-step explanation:
a) if the population at the beginning of the year 2000 was 7500 people,
The 1-year percent change in the city's population would be
3.6/100 × 7500 = 270
b) The population after 1 year is
7500 - 270 = 7230
The percentage of the previous value of the population to its new value for each year is
7230/7500 × 100 = 96.4%
c) the 1-year growth factor for the population of the city would be
(1 - 0.036)^1 = 0.964
d) the function, g that determines the population of the city (in thousands of people) in terms of the number of years t since the beginning of 2000 would be
g = 7500(1 - 0.036)^t
g = 7500(0.964)^t
To find the average, add them all up. 13 + 7 + 12 + 9 + 8 + 8 + 16 = 73
Then divide by how many numbers there are, 73 divided by 7 = 10.4285714286
10.4285714286 rounded to the nearest tenth = 10.4
Hope this helps :D
105 was the number of pgs Jorge read was because 15×7 equals 105
Answer:
t = 16/3
Step-by-step explanation:
4/3 : 7= 3t/4 :21
4/3 x 21 = 7 x 3t/4
28 = 21t/4
112 = 21t
t = 112/21 → t = 16/3
