39) In a coordinate plane, triangle ABC has coordinates: (-1,4),(-2,5), and (5,9). If triangle ABC is reflected over the y-axis, what are the coordinates of the new
image?
A. (-1,-4),(-2,-5),(-5, -9)
B. (-1,-4),(-2,-5),(5,-9)
C. (-1,4),(-2,5),(5,9)
D. (1,4),(2,5),(5,9)
E. (1,4),(2,5),(-5,9)

Please draw it out! Thanks.

I'm so close to finishing all these.

Evaluate 4 a for a = 5 2/3 . express your answer in simplest form.

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?
