Answer:
Your answer should be 1,200 because 120 x 10 is 1,200
1. Take the two x-axis intersections.
For Q 31 it is:
x = -4 and x = 0
2. Reorganise the previous equations
x +4 = 0 and x = 0
3. Put the x side in brackets
x(x+4)
4. Done
—-
Q 32
x = -1
x = 5
x + 1 = 0
x - 5 = 0
(x+1)(x-5)
Well since it's a prediction, you can see that its a 6.2 to 10 ratio. or 62%. So if you get any KPH number, times it by 62% or times it by 0.62. To by MPH into KPH you multiply by roughly 1.6
Therfore A = 46.5
B = 32
