Yesterday karen went on a bike ride. her average speed was 10 mph. today she went on another ride this time averaging 12 mph. in the two days she biked for a combined total time of nine hours let xp the number of hours. let x be the number of hours she biked yesterday. write an expression for the combined total number of hours she biked in two days
1. plug the function into the equation.
if x=-2, -5*-2+3=13
first lets work out the equation m(x+3)
now let's add 5 to x:
so, the answer is increases by 5m
x being nathan reading, it has to be at least (or equal to) 25 or greater.
