HELP PLZ Two are true and one is not. Which of the statements is not true? Explain your answers

1) To solve -3c + 9 = 3, you would first +3 to both sides and then -9 from both sides.

2) To solve -3c + 9 = 3, you would first -9 from both sides and then divide both sides
by -3.

3) The opposite of division is multiplication.

Use the RACE method to answer. Type your answer in the box below using sentences. Your answer should have at least 2-3 sentences.

R: Restate the problem
A: Answer the question
C: isn’t used in math
E: Explain

1- is the product of two rational numbers irrational or rational? first, make a hypothesis by multiplying two rational numbers. then, use variables such as x=a/b and y=c/d and the closure property of integers to prove your hypothesis. 2- what do you think the product of a nonzero rational number and an irrational number is? is it rational or irrational? make use of variables, the closure property of integers, and possibly a proof by contradiction to prove your hypothesis. 3- why do we have to specify that the rational number must be nonzero when we determine what the product of a nonzero rational number and an irrational number is? if the rational number were 0, would it give us the same result we found in part b?
