Answer:

  x = {-9, -4, -3/2}

Step-by-step explanation:

The zeros are the values of x that make the factors zero. (If a factor is zero, the product will be zero.)

<u>x+4 = 0</u>

  x = -4 . . . . subtract 4

<u>2x+3 = 0</u>

  2x = -3 . . . . subtract 3

  x = -3/2 . . .  divide by 2

<u>-x-9 = 0</u>

  -9 = x . . . . add x

__

The zeros are ...

  x = {-9, -4, -3/2}

Answer:

Mode: 100

Mean: 46.94444...

Median: 29.5

Range: 150

Step-by-step explanation:

Mode: most occurring number: 100

Mean: Plus everything and divide by how many number there is: 845/18=46.94....

Median: The middle number, but you need to line it from smallest to greatest.

0, 0, 0, 1, 3, 4, 5, 12, 29, 30, 40, 50, 100, 100, 100, 100, 121, 150

29 and 30 is in the middle. In this case, you plus 29+30 and divide by 2. =29.5

Range: Largest number-Smallest number. You also need to line it from smallest to largest: 150-0=150

Hope this helps, BRAINLIEST would really help me:)

You have used the Distributive Property totransform numerical expressions such as (5)(3) +(2)(3) to (5 + 2)(3). How would you tr
barxatty [35]

We have the expression

5x+2x

We have to convert the expression in a single-term expression. We apply the distributive property:

5x+2x=(5+2)\cdot x=7x

b) We have to substitute five different values into the expressions 5x+2x and 7x-1.

The first expression is equal to 5x+2x=7x.

We then can predict that the difference between 7x and 7x-1 is 1.

For example, for x=2, we have 7x=7*2=14 and 7x-1=7*2-1=14-1=13.

We can calculate if the two expressions can be equal, we write:

\begin{gathered} 5x+2x=7x=7x-1 \\ 7x=7x-1 \\ 7x-7x=-1 \\ 0=-1\longrightarrow\text{False} \end{gathered}

There is no value that can make both expressions equal.

Both equations have a difference of 1 for any value of x.
