Answer:

option D

\frac{4x-8}{-2x^2}

Step-by-step explanation:

An expression is undefined when you get division by zero or in simple words when denominator is zero.

Now we will solve each expression one be one by plugging value of x = 0

<h3>1)</h3><h3>\frac{5x^2-4}{3x-3}</h3>

\frac{5(0)-4)}{3(0)-3}

-4/-3 = 4/3

<h3>2)</h3><h3>\frac{6x^2}{9x-3}</h3>

\frac{6(0)}{9(0)-3}

0/-3 = 0

<h3>3)</h3>

\frac{8x+6}{-x^2+1}

\frac{8(0)+6}{-0+1}

6/1

6

<h3>4)</h3>

\frac{4x-8}{-2x^2}

\frac{4(0)-8}{-2(0)}

<h3>-8/0</h3><h3>undefined</h3>

Mr. Young is offered an investment opportunity. Kyra says she will invest his money at a 6% simple interest rate over the next 7
gregori [183]

Answer:

$126

Step-by-step explanation:

Given that:

Investment is done as per Simple interest.

Principal = $3000

Time for which the investment is to done = 7 years

Rate of interest = 6%

To find:

Interest earned when the investment matures?

Solution:

Formula for Simple Interest :

Simple\ Interest = \dfrac{PRT}{100}

Where P is the principal amount

R is the Rate of Interest

T is the time for which the investment is made

Putting the given values:

Simple\ Interest = \dfrac{3000\times 6\times 7}{100}\\\Rightarrow Simple\ Interest = \dfrac{12600}{100}\\Simple\ Interest = \$126

Therefore, the answer is:

Interest earned is <em>$126</em>.

Which set of graphs can be used to find the solution set to 3e* &gt; &gt;-x?
kobusy [5.1K]

The attached graph represents the solution set of 3e^x > \frac 12^x

<h3>How to determine the graph?</h3>

The complete options are not given.

So, I would plot the graph that represents the solution set

The inequality is given as:

3e^x > \frac 12^x

Start by splitting the inequalities as follows:

f(x) > 3e^x

g(x) > \frac 12^x

The above means that we plot the graphs of f(x) and g(x) to represent the solution set

If the area of the rectangle is 90 km?, then what is the value of the missing side?
r-ruslan [8.4K]
I believe it would be B.
Logically, it’s the only one that makes sense,
As 9x10= 90
None of the others have any way to divide or multiply up to the area,
So yes, B.
