Answer:

Step-by-step explanation:

I am assuming they are not allowing graphing calculators for this, which is kind of wacky, if you ask me.

Anyway, the greater or equal to can technically be used interchangeably, so it looks like this:

y > 2x --> y = 2x

And so, with that equation, the sign just tells you what section of the graph is included. In this case, everything above the line.

Before a renovation a movie theater had 117 seats after the renovation theater had 173 what is the approximate percentage increa

aev [14]

Answer:

47.86%

Step-by-step explanation:

Total number of seats in a movie theater Before a renovation = 117

Total number of seats in a movie theater after a renovation = 173

We need to find the percentage increase of the number of seats. It can be calcualted as :

$\%=\dfrac{\text{|final number-initial number|}}{\text{initial number}}\times 100\\\\=\dfrac{173-117}{117}\times 100\\\\=47.86\%$

So, the increase in percentage is 47.86%.

To solve this system of equations by elimination, what operation could be used to eliminate the x-variable and find the value of

gayaneshka [121]

The system of equations are:

2x − 4y = 6
−3x + 3y = 9

To eliminate x, you should:
1. multiply first equation with 3
2. multiply second equation with 2
3. add the new equations you got

So your answer is A.

Choose the correct simplification of x to the 12th power times z to the 11th power all over x to the 2nd power times z to the 4t

Umnica [9.8K]

Answer:

<h3>The option A) $x^{10}z^7$ is correct answer.</h3><h3>The correct simplification for the given expression $\frac{x^{12}\times z^{11}}{x^2\times z^4}$ is $x^{10}z^7$ </h3>

Step-by-step explanation:

Given expression is x to the 12th power times z to the 11th power all over x to the 2nd power times z to the 4th power.

The given expression can be written as $\frac{x^{12}\times z^{11}}{x^2\times z^4}$

<h3>To choose the correct simplification of the given expression :</h3>

Now we have to simplify the given expression as below

$\frac{x^{12}\times z^{11}}{x^2\times z^4}$

$=x^{12}\times z^{11}(x^{-2}\times z^{-4})$ ( by using the identity $\frac{1}{a^m}=a^{-m}$ )

$=(x^{12}.x^{-2})\times (z^{11}.z^{-4})$

$=x^{12-2}\times z^{11-4}$ ( by using the identity $a^m.a^n=a^{m+n}$ )

$=x^{10}\times z^7$

$=x^{10}z^7$

∴ $\frac{x^{12}\times z^{11}}{x^2\times z^4}=x^{10}z^7$

<h3>The correct simplification for the given expression $\frac{x^{12}\times z^{11}}{x^2\times z^4}$ is $x^{10}z^7$ </h3><h3>Hence option A) $x^{10}z^7$ is correct answer.</h3>
