I don't know how to solve for these can yall help ? 1) 9 x + 8 + 10 < 55 2)1 − 4k ≥ −11
3)9 m − 8 − 10 < 26

What is the name used to describe a graph where for some value of x, there exists 2 or more different values of y?

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?

Can someone me with the property questions for 12 13 and 14 plz
