The difference of b and 4 is at most 15.

b - 4 ≤ 15

b ≤ 19

Step-by-step explanation:

The statement "at most" typically means no more than, so the inequality sign would have to be "less than or equal to"

To solve for be all you would do is add 4 to both sides to get b by itself.

b - 4 ≤ 15

b - 4 + 4 ≤ 15 + 4

(-4 + 4 cancels itself out)

(15 + 4 = 19)

b ≤ 19

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..
