Solve the equation for y and simplify.<br> x - 6y = 48
Kipish [7]
Start by simply rewriting the equation
x-6y=48
Then transfer any other variables or numbers through addition or subtraction so that the y is isolated on one side of the equals sign
(in this case, subtract the x so that it moves to the other side of the equal sign)
-6y =48 -x
Finally, do any multiplication or division to cancel out anything still attached to the y.
y = -8 +\frac{x}{6}
(in this case, divide by -6)
Now the y has been fully isolated on one side of the equal sign and you can see that x - 6y = 48, solved for y, is <span>y = -8 +\frac{x}{6}.
I do not see any way to simplify this further, though it is possible I am missing something.</span>

96/8 + {2(5-7) exponent 2 + 4}
Makovka662 [10]

Answer:

24

Step-by-step explanation:

96/8 + {2(5-7) exponent 2 + 4}

= 96/8 + {2(-2) exponent 2 + 4}

= 96/8 + {2(4) + 4}

= 12 + {8 + 4}

= 12 + 12

=24

Answer:

Factors: (x²y+6)(y²-11)

<h2 />

Step-by-step explanation:

Here's the original equation.

x²y³ - 11x²y + 6y² - 66

Let's separate it into two groups to make it easier.

(x²y³ - 11x²y) + (6y² - 66)

Let's take a look at (x²y³ - 11x²y) first. Do we notice anything that can be removed from the parentheses?

Yes, x²y can be taken from both polynomials to simplify the contents of the parentheses.

Both polynomials have x² and both have at least one y. Combine that to get x²y. That means that within the parentheses y² and - 11 will be left.

So  (x²y³ - 11x²y) becomes x²y (y²-11)

This works because if we multiply x²y * (y² - 11) we get (x²y³ - 11x²)

Let's apply this same idea to (6y² - 66).

6 is the only thing in common between the two polynomials.

If we follow the same steps we get 6 (y²-11).

Notice how when we simplified both groups they each had something on the outside and (y² - 11) in the parentheses?

So lets combine the things that were on the outside of both (y² - 11).

What was on the outside of each? x²y was on the outside for the first one, and 6 for the outside of the second one.

This means that if we combine everything and simplify, the factors we have are (x²y+6)(y²-11).

If you want to confirm, work your way backwards using the distributive property. You'll find that when you multiply (x²y+6) * (y² -11) you'll get = x²y³ - 11x²y + 6y² - 66. That was the original equation, so we know that these are the factors.

Hope that helps!
