use the elimination method to solve the system of equations. choose the correct ordered pairs 7x+3y=30 and -2+3y=3
Mariulka [41]
7x + 3y = 30
-2x + 3y = 3....multiply by -1
-----------------
7x + 3y = 30
2x- 3y = -3 (result of multiplying by -1)
----------------add
9x = 27
x = 27/9
x = 3

7x + 3y = 30
7(3) + 3y = 30
21 + 3y = 30
3y = 30 - 21
3y = 9
y = 9/3
y = 3

solution is (3,3)

Which expression is equivalent to (10x)–3? StartFraction 10 Over x cubed EndFraction StartFraction 1000 Over x cubed EndFraction
enot [183]

Answer:

\frac{1}{{1000x^3}}.

Step-by-step explanation:

You are trying to find (10x)^{-3}.

When a number has a negative exponent, that means that the number becomes a fraction. That sounds confusing, so let me show you what that would be...

\frac{1}{(10x)^{3} }

And since the 10x is being raised to the third power, it is the same thing as saying 10^3 * x^3. So, you would have...

\frac{1}{{10^3x^3}}

= \frac{1}{{10 * 10 * 10 * x^3}}

= \frac{1}{{1000x^3}}

And that's your answer!

Hope this helps!
