Answer:

15y² - 11y

Step-by-step explanation:

We have to combine like terms  in the given expression :

(7y² - 3y) + (8y² - 8y)

Here second degree term y² and y are the like terms.

So by combining these terms we can solve this.

(7y² + 8y²) - (3y + 8y)

= 15y² - 11y

Therefore, answer is 15y² - 11y

The like terms are: 7y^2 and 8y^2 -3y and -8y. Add them. 7y^2 + 8y^2 = 15y^2 -3x + (-8y) = -3y - 8y = -11y So the answer would be 15y^2 - 11y

Simplify completely: the quantity 8 times x to the third power plus 6 times x to the 2nd power minus 4 times x all over negative
True [87]
The answer is <span>a.−4x^2 − 3x + 2
</span>
the quantity 8 times x to the third power plus 6 times x to the 2nd power minus 4 times x all over negative 2 times x is: \frac{8 x^{3}+6 x^{2} -4x }{-2x}

\frac{8 x^{3}+6 x^{2} -4x }{-2x} =  -\frac{8 x^{3}+6 x^{2} -4x }{2x}=- \frac{2x*4 x^{2} +2x*3x-2x*2}{2x} =- \frac{2x(4x^{2} +3x-2)}{2x} = \\  \\ =-(4x^{2} +3x-2)=-4x^{2} -3x+2

Name the property the equation illustrates.<br><br> 7 + (4 + 4) = (7 + 4) + 4
galben [10]

Answer: Associative Property of Addition

Step-by-step explanation: The statement 7 + (4 + 4) = (7 + 4) + 4 represents the associative property of addition. Notice that the addends or the numbers we are adding are the same on both sides of the equals sign.

But on the left side, 4 and 4 are grouped together and on the right side, 7 and 4 are grouped together.

The <em>associative property of addition</em> says that when we are adding more than two numbers, the grouping of the addends does not affect the sum.

Here, the order operations tells us to begin inside the parentheses. So we have 4 + 4 which is 8 and 7 + 8 is 15.

On the right side, notice that 7 + 4 is 11 and 11 + 4 is also 15.

In general terms, we can write the associative property of addition as

(a + b) + c = a + (b + c) where <em>a</em>, <em>b</em>, and <em>c</em> are variables that can represent any number.

Zach has 3/4 hour to play video games. It takes him 1/12 hours to set up the system. Each round of his favorite game takes 1/6 h
tiny-mole [99]
1/12 + 1/6x = 3/4...multiply everything by common denominator of 12
1 + 2x = 9
2x = 9 - 1
2x = 8
x = 8/2
x = 4 <== he can play 4 rounds
