So first we want to distribute. (#1)

So, using the distributive property, we can:

5 * 3x - 2y * 5 + 2x + 2 * 2y - 3 * 3x - 3 * 2y

or

15x - 10y + 2x + 4y - 9x - 6y

Now just combine like terms

8x -12y

So for #1 it should be a.

#2: 2x - 3 + 3x - 5

Combine Like Terms:

2x + 3x - 3 - 5

5x - 8

So it should be b.

HELP ASAP <br> H(x)=-6x+8<br> G(x)=10-2x<br><br> H(G(x))

galben [10]

<u>Answer:</u>

H(G(x)) = 12x - 52

<u>Step-by-step explanation:</u>

We are given the following two functions:

$H ( x ) = - 6 x + 8$

$G ( x ) = 1 0 - 2 x$

And we are to find the value of H(G(x)).

For that, we will apply the function of H on the function of G.

$H(G(x))=H(10-2x)$

$H ( G ( x ) ) = - 6 ( 1 0 - 2 x ) + 8$

$H(G(x))=-60+12x+8$

H(G(x)) = 12x - 52

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
