6 hours before is 9pm
3/4=45/60
add 45+37=72-60=12=1+9=10:12
Ƒ(x) = 2x and g(x) = 3x?
The question means at which points (or coordinates) f(x) & g(x) intercepts.
In this case you proceed as follows:
f(x) =g(x)==> 2x = 3x or 0 = x if x = 0 , y also =0 then both graphes passes through the origin O (0,0)
