is the study of algebraic equations on graphs
An example of the coordinate geometry is plotting point,lines and curves on
an x & Y axis thanks
3x(x^2+4)
3x(x^2)+3x(4)
=3x^3+12x
Let X = the number of hours
Plane 1 equals: 850x
Plane 2 equals: 750x
850x + 750x = 4000
1600x = 4000
x = 4000 / 1600
x = 2.5 hours
3 pm + 2.5 hours = 5:30 pm
