Jack's age is three years more than twice his younger brother jimmy's age if the sum of their ages is at most 18 find the greatest age that jimmy could be.

o= 4(i) +3

step-by-step explanation:

o is your output value and i is your input value. so, for example, if we stuck 7 in as our input, we would first multiply by 4 ( pemdas ), which equals 28. then we would add 3 to 28, for a total output of 31. this may not be a graph, but, it is a way to solve your formula..

i believe the answer is d.

hope it you! : d
