Answer:
Step-by-step explanation:
It looks like your interactive graphing tool needs you to plot some points on each of the lines. For these lines, it is convenient to use the x- and y-intercepts. Each intercept can be found by dividing the constant by the coefficient of the variable.
<u>-7x -2y = 14</u>
The x-intercept is 14/-7 = -2. Plot (-2, 0) on the x-axis.
The y-intercept is 14/-2 = -7. Plot (0, -7) on the y-axis.
<u>6x +6y = 18</u>
The x-intercept is 18/6 = 3. Plot (3, 0) on the x-axis.
The y-intercept is 18/6 = 3. Plot (0, 3) on the y-axis.
__
The point of intersection of the two lines is the solution: (x, y) = (-4, 7).
Answer: a 470
Step-by-step explanation:
The exponential growth equation with rate of growth r in time period t is given by :-
, where A is the initial amount
Given : The rate of growth of population every year : 0.9% =0.009
The initial population = 430
Then , the exponential growth equation in time period t is given by :-
In 2010 or for t= 10 years
The projected population of the town will be :-
Hence, the projected population of the town in 2010 is about 470.
