Answer:

The domain of the function is x>=-7

Step-by-step explanation:

The domain is all the values that x can take so the function is defined, that means we can find a value of y

The sqrt is defined only for positive values and zero. So the expression in the sqrt must satisfy that

6x + 42 >=0

We only have to find x

6x >=-42

x>=-42/6

x>=-7

So the answer is D x>=-7

Someone plz help me with this

Phoenix [80]

Answer:

$5y^{6}\sqrt{2}$

Step-by-step explanation:

We want to simplify:

$\sqrt{50y^{12}}$

We rewrite as:

$\sqrt{2\times25 \times (y^{6})^2}$

We split the radical sign to obtain:

$\sqrt{25} \times \sqrt{(y^{6})^2} \times \sqrt{2}$

Simplify the square root for the perfect squares to get:

$5y^{6}\sqrt{2}$

Therefore the simplified form is: $5y^{6}\sqrt{2}$

What is 26.99 round to the nearest tenth

Arte-miy333 [17]

Salutations!

To round to the nearest tenth, you need know whether the number next to tenth place is greater than 5 or lesser than 5. If its greater than 5, you need to round up. If its lesser than 5, you need to round down. Now, in the number 26.99 9 is in the tenth place. The number next to 9 is greater than 5, so just add on to the ones place, making the tenth and hundredth place 0. Zero has no value so whether you add the zero or not, it does not matter.
