Answer:

(3,3)

Step-by-step explanation:

To find the y - value that corresponds to x=3 , substitute the x - value in the equation.

y=4x-9

y=4*3-9

y=12-9

y=3

Therefore, (3/3) is the solution to the equation.

Help!!!!!!!!!!!! >>>>>Which number set contains all rational<br> numbers?

stellarik [79]

The only set that only has rational numbers is the first one:

{1/3, -3.45, √9}

<h3>Which of the given sets contains only rational numbers?</h3>

A rational number is a number that can be written as the quotient of two integers.

If we look at the first set, the elements are:

1/3 which is a rational number.
-3.45 = -345/100 which is a rational number
√9 = 3 = 3/1 which is a rational number.

In the other sets we can see elements like:

√37, √44, or √2 which are all irrational numbers, then the only correct option is the first one.
