Answer:
Step-by-step 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
