Determine whether each statement is true or false:
a. for all real numbers x, there exists a real number y such that ? ? ? 5 ? ? ? 1 = 0 is true.
b. there exists a real number x, such that for all real numbers y, ? ? ? 5 ? ? ? 1 = 0 is true.
13. determine whether each statement is true or false:
a. ? ? ? ? ? ? = ? ? + 1.
b. ? ? ? b ? ? ? b, ? ? ? b ? ? = ? ? ?

the answer to your question is b.

proportions are fractions that equal to each other. so if two fractions are the same, they are proportional.

let's check the answers to see if they are proportional.

question a is not proportional because you can't turn 1.5/3 to 3/9. if you try to multiply 1.5/3 by 2 or 3, you wont get 3/9. it's impossible to make the fractions the same.

question b is not proportional because you can't turn 22/33 to 4/6. 33 can't go into 6.

question c is proportional because when you multiply 2 and 3 by 71, you would get 142/213, and those fractions equal to each other

question d is proportional because when you divide 14 and 7 by 2, you would end up with 7/3.5, and those fractions equal to each other.
