I need help writing this! Using: g(x) = a(x – h)+k

How would the following description be written based g(x) = a(x – h)+k?

Reflection over x-axis, Vertical Compression
by a factor of 2/3, vertical shift up 5

This is different from the first one can someone me

What is the order of these fractions from least to greatest 2/3 7/10 5/8 65/100

1- 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.2- 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 the first question?
