Answer:
y =
Step-by-step explanation:
given that y and x are proportional then the equation relating them is
y = kx ← k is the constant of proportionality
to find k use the given condition y = 12 when x = 5
k = =
y = x ← equation of proportionality
when x = 8, then
y = × 8 =
Let time be t , distance be d
Put value in eq(2)
Answer:
It is the value of the coin when it was originally purchased. t=0 y=3
Step-by-step explanation:
The y intercept is the value when t=0
It is the value of the coin when it was originally purchased. y=3
Divide 140 by 5 = 28
