Given
F(x) = (3x - 12) + 2, what is the domain in set notation?
O {x|x ER, X2 4}
O {x|x ER, XS4}
{x|x ER, X2}
O {x|x ER, XS 2

Answer:

The only thing I can think of is -2.

Step-by-step explanation:

-9 + 7 = -2

I'm not sure if you wrote the questions or the answers wrong, but if I'm reading it right the answer should be -2, not 2. Unless you meant to write 9 + -7, in which case the answer would be 2.

Given parameters:

 Let us solve this problem step wisely;

  Let the number  = x

              6 + x

            (6 +  x)²

The algebraic interpretation is (6 +  x)²

In problems like this, it is best to first choose a variable and then solve following sentence by sentence.

Answer: x = -2.5

Step-by-step explanation:

Subtract 5 on each side to get -2x = 5

then divide both sides by -2 to get x = -2.5.

Answer:

Step-by-step explanation:

Starting with ...

  I = V/R

Multiply by R to find V:

  IR = V

The equation is ...

  V = I·R

__

Using the given values for I and R, we have ...

  V = (2)(6)

  V = 12 . . . required voltage (volts)

Answer:

Let it be for x miles.

40+15+0.25x=45+0.35x

10 =0.1x

x=100

The mile is 45+0.35*100= 80 or 40+15+0.25*100 =80

Step-by-step explanation:

Answer:

x=100

Answer:

no solution

Step-by-step explanation:

3 - 6а = 9 - ба

Add 6a to each side

3 - 6а+6a = 9 - ба+6a

3 = 9

This is never true so there is no solution

Answer:

x = -1

Step-by-step explanation:

so first rewrite the equation in numerical terms

5x + 6 = 1

now solve with inverse operations

5x + 6 = 1

    -6     -6

5x = -5

/5     /5

x = -1

Answer:

A. y=cos(x)

Step-by-step explanation:

I just want the points. im taking the quiz rn.

From the given options, the only even function is the cosine function, so the correct option is A.

First, an even function is a function with the property:

f(x) = f(-x)

So these functions are symmetrical across the y-axis.

Is ratter easy to remember that the sin function is actually odd, this means that:

sin(-x) = -sin(x).

Then the tangent function (and the cotangent function) are also odd, because:

tan(x) = sin(x)/cos(x).

In the other hand, for the cosine function we have:

cos(-x) = cos(x)

And as shown in the graph below, it is symmetrical across the y-axis.

Then we conclude that the correct option is A.

Answer:

$1000

Step-by-step explanation:

So there is 10,000,000 dollars in the company for the annual employee bonus. There are 10,000 employees in this company. This seems like a simple division problem. So you divide 10,000,000 by 10,000 and you get 1,000. So with that being said each employee should receive $1,000 in total.

This may be wrong if so I tried my best

Answer:

-0.4 should be in between 0 and -0.5, however be as close to -0.5 as possible while not being ON -0.5.

3 4/5 should be in between 3 and 4, so you can split 4/5 into 8/10 which are equal to each other. Then you can pretend to split the 3 and 4 gap into 10 equal pieces. After you split the gap, count 8 parts to the left of 3.

Step-by-step explanation:

Given

Perimeter = P

Required

Determine the area

First, we need to calculate the sides of the square using:

[tex]P = 4L[/tex]

Where L represents the length of the side

Make L the subject

[tex]L = \¼P[/tex]

Area is calculated as thus:

[tex]Area = L\²[/tex]

Substitute ¼P for L

[tex]Area = (\¼P)\²[/tex]

Answer:  a) the dependent variable is y, the amount he earns depending on x, the independent variable. x is the number of hours.

b) y = 5x + 10

c)  Bobby earns $27.50 for the 3.5 hour job

Step-by-step explanation: use the function y=5x + 10  substitute 3.5 for x

y = 5(3.5) + 10

y = 17.5 + 10

y= 27.5
