Answer:
The pair (0,3) is not a solution to the equation
Step-by-step explanation:
This can be proved by simply replacing the x and y variables in the equation by the x and y values of the pair, and checking if the equation renders a true statement:
By replacing x and y with their values in the pair (0,3), that is x=0 and y=3, in the equation y = 5 - 2x we get:
3 = 5 - 2 (0)
3 = 5 - 0
3 = 5
which is NOT a true statement.
On the other hand, the other two pairs (2,1) and (1,3) render true statements:
1 = 5 - 2 (2)
1 = 5 - 4
1 = 1
and
3 = 5 - 2 (1)
3 = 5 - 2
3 = 3
Answer:
12,633.7
Step-by-step explanation:
population of Chicago, in 2003 = 2,869,121
The area of Chicago = 227.1 square miles.
What was the average number of people living in 1 square mile?
Average number of people living in 1 square mile also refers to the population density of Chicago
Average number of people living in 1 square mile = Total population / total square miles
= 2,869,121 / 227.1
= 12633.734037868
Approximately
12,633.7
Answer:
a = 72
Step-by-step explanation:
Subtract 56 from both sides of the equation so you can isolate the variable
128-56=72
