you just flip the slope, make it the opposite of what you started with.
put one on hereeee
f = - 15x +700
let's solve for f.
step 1: divide both sides by x.
let n represent the number
twice the number =2n
4 times the number = 4n
given that twice the number is atleast 3 less than four times the number
algebraically this can be written as
we can add 3 to both sides
so n should be atleast 1.5
if n is natural number or integer then least value of n is 2.
