z + 18 = y
Reorder the terms:
18 + z = y
Solving
18 + z = y
Solving for variable 'z'.
Move all terms containing z to the left, all other terms to the right.
Add '-18' to each side of the equation.
18 + -18 + z = -18 + y
Combine like terms: 18 + -18 = 0
0 + z = -18 + y
z = -18 + y
Simplifying
z = -18 + y</span>
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
Answer:
c. x = 27
Step-by-step explanation:
-11 + 1/3 x + 9 = 7
1/3 x - 2 = 7
1/3 x = 9
x = 27
