Right now the dirt bike is worth $500. Next year it will be worth 15% less, or 85% of the current value (because currently it's at 100%, so you would subtract the 15%). To find 85% of the dirt bike's value, you would take $500 and multiply by 85% (or 0.85). This would give you $425 after 1 year. You'd take $425 and multiply that by 85% for the next year, and continue until you reached 5 years of the value decreasing. Does this help?
Alright, so the answer for:
3) is 3v + 4
If the preimage point is (5,0) and the image point is (10,0)
then the scale factor is k = 2
Basically the coordinates of the old point have doubled (multiplied by 2)
x = 5 is the old x coordinate
x = 10 is the new x coordinate (5*2 = 10)
y = 0 is the old y coordinate
y = 0 is the new y coordinate (0*2 = 0, no change)
