Answer:

  (-∞, ∞)

Step-by-step explanation:

The domain of a function is the set of values of the independent variable for which the function is defined. On a graph, it is the horizontal extent of the graph.

The domain of any polynomial function is "all real numbers." There are no values of x for which f(x) is undefined.

In interval notation, the domain is ...

  (-∞, ∞)

Answer:

Any of these are correct:

1/1001, 1/1002, 1/1003

1/2000, 1/2358

1/10000

2/3000= 1/1500

3/4000

so many!

Step-by-step explanation:

Anything that is positive and not negative will be bigger than zero.

Anything with a 1 on top (numerator) and LARGER than 1000 on the bottom (denominator) will be less than 1/1000.

OR you can change 1/1000 by multiplying 2/2 or 3/3 or 4/4 or 5/5 etc. Then lower the top number only. Example:

1/1000 × 5/5 = 5/5000

(multiply straight across: top×top and bottom×bottom)

Then shrink the top:

3/5000

It is 39

Because you have to count the little dots all the way till it is around the most age.

Based on the definition of the formula unit, the only one that is an example of this concept is NaCl.

In chemistry, this concept refers to the representation of an ionic compound. This formula differs from others because it displays the lowest possible ratio in which the ions have the same charges and therefore the compound is neutral.

A classical example of this concept is NaCl because this includes a cation (positively charged) and an anion (negatively charged). Moreover, in this formula, the compound shows the lowest possible ratio between the two elements.

Answer:

745.31+50.60w=1,099.51

W=7

Step-by-step explanation:

1st subtract 1099.51 from 354.20

2nd use your answer which is 745.31 and add that with how much she plans on saving for how ever long

3d to find out how many weeks which is 50.60*w you need to first minus 745.31 from both sides

4th so 745.31- 745.31 and 1099.51-745.31 =354.2 or .20

5th divide 354.2 by 50.60 =7

So overall w= 7

Hence,

1st x value

2nd x value

The roots are 3 and -5/2.

Answer:

x = 25,

Step-by-step explanation:

(4x + 3) + (2x + 27) = 180 (Told they were a linear pair) (supplementary)

6x +30 = 180 (Combine like terms)

6x = 150 (Subtract 30 from both sides)

x = 25 (Divide both sides by 6)

m<RQS = 4(25) + 3

= 103 degrees

m<TQS = 2(25) + 27

= 77 degrees

Answer:

X+Y=10, X-Y=2, what is X, Y?

Answer: x=6 and y=4

Explanation:

Given:

x+y=10 ⟶(i)

x−y=2 ⟶(ii)

From equation (ii) ,

x=2+y

Put value of x in equation (i) ,

2+y+y=10

2+2y=10

2(1+y)=10

1+y=102

1+y=5

y=5−1

y=4

Put value of y in equation (ii) ,

x−4=2

x=2+4

x=6

x + y = 10 → Eq A

x – y = 2 → Eq B

Now we will take out the expression of x from Eq A.

x + y = 10 Eq A

x = 10 – y → Expression of x

Now put the expression of x in Eq B.

x – y = 2

( 10 – y ) – y = 2

10 – 2y = 2

10 – 2 = 2y

8 = 2y

y = 8 / 2

y = 4

Now put the value of y in expression of x.

x = 10 – y

x = 10 – 4

x = 6

So, x = 6 and y = 4.

Thank you.

Hope it helps and you like it

x + y = - 10 (equation 1)

x - y = 2 (equation 2)

using equation 2 we get x = 2 + y

putting the value of x in equation 1 we get :

(2 + y) + y = - 10

2 y = -10-2

2 y = -12

y = -6

put the value of y in any equation

to get the value of x

x - y = 2

x - (-6) = 2

x + 6 = 2

x = -4

The correct matches are:

32 corresponds to log₂(x) = 5

3 corresponds to log₃(x) = 1

1,000 corresponds to log₁₀ (x) = 3

625 corresponds to log₅(x) = 4

16 corresponds to log₄(x) = 2

A logarithm is a mathematical function that represents the exponent to which a specific base must be raised to obtain a given number. In other words, it is the inverse operation of exponentiation.

The logarithm of a number x to a given base b is denoted as log_b(x), where b is the base and x is the number. It represents the power to which the base must be raised to obtain the value x.

The logarithmic equations and their corresponding x-values are as follows:

log₂(x) = 5 → x = 32

log₃(x) = 1 → x = 3

log₁₀(x) = 3 → x = 1,000

log₅(x) = 4 → x = 625

log₄(x) = 2 → x = 16

So, the correct matches are:

32 corresponds to log₂(x) = 5

3 corresponds to log₃(x) = 1

1,000 corresponds to log₁₀ (x) = 3

625 corresponds to log₅(x) = 4

16 corresponds to log₄(x) = 2

Remark

√-12  

The square root of -12 must have an i in it somewhere. If it does not, then the minus sign stays under the root sign. If you take the root of -1 you get i, and that is outside √ sign.

Solution

A is incorrect. i is on the outside of the root sign.

B is the answer.

C does not seem to take the square root of anything except -1 so it is incorrect.

D Has no i anywhere and the -1 is incorrectly placed. D is wrong

E is just wrong. The minus should disappear once the square root of -1 is taken. 12 has a root that has not been declared.

Answer: 146°

Step-by-step explanation:

Answer:

x = 2 or x = 3

Step-by-step explanation:

x² - 5x + 6 = 0

x² - (3 + 2)x + 6 = 0

x² - 3x - 2x + 6 = 0

x(x-3) - 2(x - 3) = 0

(x - 3)(x -2) = 0

Either,

x - 3 = 0

x = 3

Or,

x - 2 = 0

x = 2
