1) The population of an island is 6,000 people this year and is expected to be 6,300 people next year. a) By what percent is the population increasing?
b) If this trend continues, what will be the population 8 years from now? c) If this trend has continued for
several years, when was the population 4,000 people?

Step-by-step explanation:

a) 5%

6300-6000=300

300/6000×100%=5%

b) 8700

the population keeps on increasing by 300 more pple,hence every year plus 300

the system of inequalities is

step-by-step explanation:

step 1

find the equation of the dashed line

we have the points

(0,0) and (3,1)

the line passes through the origin, so, is a direct variation

find the slope

the equation of the dashed line is

the solution of the inequality a s the shaded area above the dashed line

therefore

the equation of the inequality a is

step 2

find the equation of the solid line

we have the points

(4,0) and (0,4)

find the slope

the equation of the solid line is

the solution of the inequality b s the shaded area below the solid line

therefore

the equation of the inequality b is

step 3

the system of inequalities is
