Answer:

Step-by-step explanation:
The first equation is 
The second equation is 
When we graph these two equations, <em>they will meet at a point which represent the solution of the two equations</em>.
We can solve the two equations simultaneously to determine their point of intersection.
Let us substitute the second equation into the first equation to get;

Multiply through by 2 to get;

Group similar terms to obtain;

Simplify;

Divide both sides by 3;

Put
into the second equation;



Therefore the graphs of the two functions intersect at (2,3)

Answer:
That is 74 years.
Step-by-step explanation:
1.5% = 0.015.
The equation for the rate of growth is P = 430,000(1.015)^n where n is the number of years.
Triple the population is 430,000 * 3 = 1,290,000, so:
1,290,000 = 430,000(1.015)^n
(1.015)^n = 1290,000 / 430,000 = 3
Taking logs of both sides:
n log 1.015 = log 3
n = log 3 / log 1.015 = 73.8 years
30=(10*3*x)/2
*2 *2
60=10*3*x
60=30x
60/30=30x/30
2=x
