The unit rate of the proportional relationship y = 3x is 3
<h3>How to determine the unit rate?</h3>
The proportional relationship is given as:
y = 3x
Divide both sides by x
y/x = 3
For a proportional relationship y/x = k;
The unit rate is 3
This means that the unit rate of the proportional relationship y = 3x is 3

Answer:
The two roots of the quadratic equation are

Step-by-step explanation:
Original quadratic equation is 
Divide both sides by 9:

Add
to both sides to get rid of the constant on the LHS
==> 
Add
to both sides

This simplifies to

Noting that (a + b)² = a² + 2ab + b²
If we set a = x and b =
we can see that
= 
So

Taking square roots on both sides

So the two roots or solutions of the equation are
and 

So the two roots are

and
