The measurements from an experiment were recorded in the following table:
x(seconds) (0), (10), (20), (30), (40), (50)
y(metres) (1500), (1200), (900), (600), (300), (0)
Using suitable scales, draw a graph to illustrate the results of the experiment. Use your graph to answer the following questions:
---
Equation: y = -30x+1500
a) Find the value of y when x is
i) 5, ii) 18, iii) 25, iv) 45, v) 47.
f(5) = -30*5+1500 = 1350
f(18) = -30*18+1500 = 960
etc.
-------------------------------------------
b) Find the value of x when y is
i) 1455, ii) 990, iii) 480, iv) 390, v) 270.
1455 = -30x+1500
-45 = -30x
x = 1.5
------------------
990 = -30x+1500
-30x = -510
x = 17
etc.
