Which method would be best (quickest) for solving the system below:<br> 3x - 4y = -2<br> y = 2x + 1
taurus [48]
To solve with Elimination:

Write the equations under one another, like this:

2x - y = -1
+ 3x + 4y = 26

Ideally, we would like for one of the variables to be eliminated when we add vertically (straight down). But if we add them as they are this does not happen. We must manipulate one of the equations so that it will happen. Again, you can try to eliminate either x or y. I always look for a term that has a coefficient of 1 (or negative 1). So, let's use that y from the first equation again.

If the coefficient of the y in the other equation is POSITIVE 4, then I need the coefficient from the first equation to be its opposite, NEGATIVE 4. To do this, simply multiply the first equation by 4, this will create MAGIC!

4( 2x - y = -1)
+ 3x + 4y = 26

Be certain to Distribute across the entire first equation, so multiply all three terms by 4.

8x - 4y = -4
+ 3x + 4y = 26

Now add straight down (vertically). The y term will be eliminated.

11x = 22

Divide both sides of the equation by 11.

x = 2

Almost there! Now, substitute the 2 in for x in either of the original equations. Either one will work. I'm gonna use the second equation.

3x + 4y = 26

3(2) + 4y = 26

6 + 4y = 26

Subtract 6 from both sides of the equation.

4y = 20

Divide both sides of the equation by 4.

y = 5

That's it! There it is again. Put it all together. If x = 2 and y = 5, then the solution is the ordered pair, (2,5).

On average, 15 minutes elapse between discoveries of fraudulent corporate tax returns in a certain IRS office. What is the proba
Lyrx [107]

Answer:

The probability that more than 30 minutes will elapse before the next fraudulent corporate tax return is discovered=0.1353

Step-by-step explanation:

We are given that

\beta=15

We have to find the probability that more that 30 minutes  will elapse before the next fraudulent corporate tax return is discovered.

Using exponential distribution

P(X> x)=e^{-\frac{x}{\beta}}

The probability that more than 30 minutes will elapse before the next fraudulent corporate tax return is discovered

=P(x>30)=e^{-\frac{30}{15}}

The probability that more than 30 minutes will elapse before the next fraudulent corporate tax return is discovered

P(x>30)=0.1353

Hence, the probability that more than 30 minutes will elapse before the next fraudulent corporate tax return is discovered=0.1353
