Maths
Question 2
When typing in a calculator, ½ × 3 gives a different answer than 1/(2 × 3). With that mind classify
these equations as true or false.
True
False
1/(ab) = 1/ab
1/(ab) = 1/a/b

(1/a)b = 1/(ab)
1/ab = b/a
1/ab = (1/a)b

Question 10
Use the graph to determine the units of the slope and the y-intercept.
Unit of slope : m/s
y-intercept unit: s
Solution
Slope = gradient.... The gradient is represented by latter m
M = (y² - y¹)/(x² - x¹)
Change in y/change in x = change in distance (s) /change in time (t)
S/t = v
Since s is given in unit metre(m) and time is given in seconds (s)
Therefore our slope = velocity which is measured in m/s
y-intercept = distance... Which is measured in metre (m) the graph intercept at y axis.

Question 25
Consider the system of linear equ...
