Answer 1

Answer:

linear regulation = 2y+5x=2000

Answer 2

Question:-

The parking charges of a car in a parking lot is Rs 20 for the first 3 hours and Rs 10 for subsequent hours. Taking total parking time to be a hours and total charges as Rs y, write a linear equation in two variables to express the above statements. Draw a graph for the linear equation and read the charges for five hours.

Answer:-

According Question,

Given:- Total Charge (y) = Rs. 20 for 3 hours + Rs. 10 for (x-3) hours.

so,

$⇒y = 10(x - 3) + 20$

$⇒y = 10x - 30 + 20$

$⇒y = 10x - 10$

$⇒10x - y = 10$

━━━━━━━━━━━━

$|x| \: \: \: \: \: \: \: \: \: 0| 1| 2|$

━━━━━━━━━━━━

$|y| - 10 |0| 10|$
