Answer:
(-3, -4)
Step-by-step explanation:
The solution is where the two lines intersect. Therefore, the x-coordinate is -3, and the y-coordinate is -4.
Another way to solve this would be to set the to equations equal to each other, so 2x+2 = -4. Therefore, 2x = -6, and x = -3. And from the second equation, y = -4.

The population of village increases by 2% every year. The current population is 1000. What will be the population after 2 years?
Answer:
1040 approx
Step-by-step explanation:
Given data
Rate = 2%
Population= 1000
Time = 2 years
We can apply the expression below to find the population after 2 years
A= P(1+r)^t
Substitute
A= 1000(1+0.02)^2
A=1000(1.02)^2
A=1000*1.0404
A=1040.4
Hence the population is 1040 approx
