Step-by-step explanation:
Given:
line C: y = x + 14
line D: y = 3x + 2
(6,20) or (3,11)
line C: y = 6 + 14 = 20 or y = 3 + 14 = 17
line D: y = 3(6) + 2 = 18 + 2 = 20 or y = 3(3) + 2 = 9 + 2 = 11
(6,20), because both lines pass through this point.
For the first one, 2/5 is the constant rate of proportionality because you are using it in a y=kx equation.
If philani buys a scooter for 15,000 and wants to pay 15% down then he must pay 2,250. After this they will still need to pay 12,750 to pay of the scooter, but after the 10% annually (for two years) then they will owe 15,750 for the scooter rather than 12,750. Hope this helps!
