Answer:
standard form of given equation is 5x - 8y = -3
Step-by-step explanation:
Standard form of linear equation is Ax + By = C
First we remove the denominator 8
We multiply the whole equation by 8
So equation becomes
8y = 5x + 3
Now we move 5x to the left hand side, we subtract 5x on both sides
-5x + 8y = 3
Now we remove the negative side from -5x by dividing the whole equation by -1
5x - 8y = -3
Answer:
population will be 79806.
Step-by-step explanation:
Population of a town 4 years ago was 50,000
Population of town had grown exponentially and present population is 63,124.
So the formula of the population growth will be
Where = Final population n = number of years.
= Initial population
r = rate of increase in population per year.
so 63124 = 50,000
= 1.0813
Now we have to find the population after 4 years from now.
=
=
= 63124 × 1.264
= 79806
Therefore, after 4 years from now population will be 79806.
