When you reverse the digits in a certain two -digit number you increase its value by 18. What is the number if the sum of its digits is 12?

option a.

step-by-step explanation:

if you look closely at the graph, we can notice that the function is not defined at two different points.

if you look at functions b and c, you will notice that both functions are not defined at just one point. the function b is not defined at x= -5/2 and function c is not defined at x=-5. both options are discarded, given that our function should not be defined at two fiferent points.

now, if you look closely at the graph you will notice that the function sketched is not defined at x=5 and x=-2.

practice. practice. practice.

the answer is a beach is the best place to be

you first to choose the points and then move from then as the slope you have
