Answer 1

Explanation:

y = 50x + 40 -----------------(I)

y = 60x + 20 ------------(II)

Substitute y = 60x + 20 in (I)

60x + 20 = 50x + 40

60x - 50x +20 = 40 {subtract 50x from both sides}

10x + 20 = 40

10x = 40 - 20 {Subtract 20 from both sides}

10x = 20 {Divide both sides by 10}

x = 20/10

x = 2

The x value of point of intersection on the graph of system of equation is 2: TRUE

2) x = 6 hours

First shop: y = 50*6 + 40 = 300 + 40 = 340

Second shop: y = 60 * 6 + 20 = 360 + 20 = 380

Tansha will pay the same amount at both auto shops if the repairs take 6 hours to complete. - FALSE
