Answer:

$y$

Step-by-step explanation:

<em>Find the equation of the dashed line</em>

The line pass through the points

$A(0,-3)$ -----> is the y-intercept of the line

$B(6,0)$

Find the slope of the line m

The formula to calculate the slope between two points is equal to

$m=\frac{y2-y1}{x2-x1}$

substitute the values

$m=\frac{0+3}{6-0}=0.5$

Remember that

The equation of the line into slope intercept form is equal to

$y=mx+b$

we have

$m=0.5$

$b=-3$

substitute

$y=0.5x-3$

<em>Find the inequality</em>

we know that

The solution of the inequality is the shaded area below the dashed line

$y$

Readme [11.4K]

Answer:

last year it was 80k

Step-by-step explanation:

Population increases by 5% every year

Last year it was 80,000

PRESENT POPULATION

Present population = 80,000 + 5% off 80,000

= 80,000 + 5/100 × 80,000

= 80,000 + 5 × 800

= 80,000 + 4,000

= 84,000

AFTER ONE YEAR

After this , the population again increases by 5%

Population = 84,000 + 5% off 84,000

= 84,000 + 5/100 × 84,000

= 84,000 + 5 × 840

= 84,000 + 4,200

= 88,200

ANSWERS

The population of present year is 84,000

After one year , the population becomes 88,200

Hope it helps :-)
