Answer:
x = 9
y = 6
Step-by-step explanation:
Let's set up equations:
x + y = 15
x - y = 3
Let's rearrange one of these equations to use the substitution method:
x - y = 3
Add y to each side:
x = y + 3
Substitute in for x:
x + y = 15
y + 3 + y = 15
Combine like terms:
( y + y ) + 3 = 15
2y + 3 = 15
Subtract 3 from each side:
2y = 12
Divide each side by 2:
y = 6
Substitute this in to find the other variable:
x + y = 15
x + 6 = 15
Subtract 6 from each side:
x = 9
Answer:
If you use the 3x to the 2y is will make more sense if u turn them into numbers instead of letters cause letters dont make much sense somtimes.
Step-by-step explanation:
The answer is: 24√6 .

The question asks:

"<span>What is the product of (3√8)(4√3)? Simplify your answer/
First, let us simplify: "</span>√8"
"√8 = √4*√2 = 2√2 ;
So, "3√8 = 3*2√2 = 6√2" .
So, "what is the product of "(3√8)(4√3)"?
Rewrite, replacing the "(3√8)" with "6<span>√2" ; as follows:
</span>6√2* 4√3 = 6*4 *√2*√3 = 24 *√(2*3) = 24√6 .

The equation of the quadratic function is f(x) = x²+ 2/3x - 1/9
<h3>How to determine the quadratic equation?</h3>
From the question, the given parameters are:
Roots = (-1 - √2)/3 and (-1 + √2)/3
The quadratic equation is then calculated as
f(x) = The products of (x - roots)
Substitute the known values in the above equation
So, we have the following equation
This gives
Evaluate the products
Evaluate the like terms
So, we have
f(x) = x²+ 2/3x - 1/9
