Answer:

-9 x^4 y^2 + x^2 y^3 - 12 x^4 y^4

Step-by-step explanation:

you combine like terms for the x^4 and y^2 terms:

      : you get -9x^4y^2

you combine like terms for the x^2 and y^3 terms:

      : you get x^2y^3

you combine like terms for the x^4 and y^4 terms:

      : you get -12x^4y^4

ps: the ^ symbol means the base to that power so (x^4 = x to the 4th power)

Hope I helped you ;)

Is y=6x-4 proportional?
bazaltina [42]

No

It is not proportional, because when x = 0, y does not equal 0.

when x = 0, y = -4. Therefore, it doesnt pass through the origin.

Jorge wants to draw a conclusion about the possible expected values of rolling a 2 on a standard die for different numbers of ro
spin [16.1K]
<span>may result in an expected value that is even, odd, or a decimal.</span> The expected value is equal to the product of the theoretical probability of rolling a 2 on 1 die roll, or <span>1/6</span>, and the number of die rolls. A total of 300 rolls gives an expected value of 50, which is even. A total of 200 rolls gives an expected value of 33.3, which is a repeating decimal. A total of 30 rolls gives an expected value of 5, which is odd.

<em>Greetings from Brasil...</em>

Here is the problem:

[(15X - 8)/3] + [(9X - 3)/2]

<em>Let's multiply everything by 6</em>

[6.(15X - 8)/3] + [6.(9X - 3)/2]

[2.(15X - 8)] + [3.(9X - 3)]

30X - 16 + 27X - 9

<h3>57X - 25</h3>
