The domain of: x+3 under square root

Mathematics

1 answer:

Gennadij [26K]3 years ago

Answer:

All real numbers except where x<-3

Step-by-step explanation:

Values of x that make negatives under even radicals are not part of the domain. Any value of x that is less than -3 would make a negative under the square root, so those are not included in the domain.

Manny plans to save 1/12 of his salary each week. If his Weekly salary is $372, find the amount he will save each week.

xxMikexx [17]

Answer:

$31

Step-by-step explanation:

We know that Manny makes $372 in a week. If he needs to save 1/12th of his salary a week, we would need to multiply 372 by $\frac{1}{12}$ .

$x=372(\frac{1}{12})$

$x=31$

This means that Manny would end up saving $31 each week.

Write an equation of the line that passes through the given point and has the given slope.

kenny6666 [7]

Answer:

2y + 3x + 7 = 0

Step-by-step explanation:

line equation = y - y1 = m (x - x1)

y - (-5) = -3/2 * (x - 1)

y + 5 = -3/2 (x - 1)

2y + 10 = -3x + 3

2y + 3x + 7 = 0

What is the solution to the equation 1^6 x = 2 ?

Dvinal [7]

1^6 is just 1 so 1x=2, you can just take away the one because it is a given that if there is an x there is a 1, so the answer is x=2

Find the mistake in the following : 3 x ( 4 + 2 ) = 12 + 2

Lyrx [107]

Answer: The mistake is improper use of distribution property.

Step-by-step explanation:

It is given that $3\times (4+2)=12+2$ .

We need to find the mistake.

The given expression is

$3\times (4+2)$

Using distribution property, we get

$3\times (4)+3\times(2)$

$12+6$

So, $3\times (4+2)=12+6$ .

In the given calculation the 3 is not distributed properly because 3 is not multiplied with 2.

Therefore, the mistake is improper use of distribution property.
