Answer:

Step-by-step explanation:

Rationalize the denominator by multiplying both denominator & numerator by the conjugate of the denominator.

Conjugate of the denominator  1 + √3 is 1 - √3

[tex]\frac{6}{1+\sqrt{3}}=\frac{6(1-\sqrt{3})}{(1+\sqrt{3})(1-\sqrt{3})}\\\\=\frac{6(1-\sqrt{3})}{(1+\sqrt{3})(1-\sqrt{3})}\\\\=\frac{6(1-\sqrt{3})}{1^{2}-(\sqrt{3})^{2}}\\\\=\frac{6(1-\sqrt{3})}{1-3}\\\\=\frac{6(1-\sqrt{3})}{-2}\\\\=(-3)(1-\sqrt{3})\\\\=-3+3\sqrt{3}[/tex]

Answer:

A. y = 6

Step-by-step explanation:

Y= 0 is equation of x - axis

 equation of any straight line which is  parallel to x-axis and at  distance of a from it is given y = c.

Therefore,  from the given option only option A y =6 is in form of y = a and hence is the correct answer.

_______________________________________

Also we know that for two lines to be parallel , their slope should be equal.

slope of line y = mx + c is m

slope of y = 0 here m = 0, hence slope is 0

out of the given option

only for y - 6 slope is 0 and hence it is the correct answer.

___________________________________

Answer: y =1

Step-by-step explanation:

Evaluating the equation for x  = 0:

y = 54 (0) + 1

y =1

The y-coordinate for the coordinate (0, y) is 1 if the coordinate (0,y) is a solution to the equation. Given the x-value of 0.

It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.

If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.

The missing figure is attached to the picture.

Calculataing  the equation for x  = 0:

y = 54 (0) + 1

y = 1

Thus, the y-coordinate for the coordinate (0, y) is 1 if the coordinate (0,y) is a solution to the equation. Given the x-value of 0.

Answer:

4%

Step-by-step explanation:

1/25 = 0.04 = 4%

Answer:

2 1/4 < x ≤ 4

Step-by-step explanation:

12x−39≤9 AND−4x+3<−6

Solve them separately and then put back together

12x−39≤9

Add 39 to each side

12x−39+39≤9+39

12x ≤48

Divide by 12

12x/12 ≤48/12

x ≤4

Now the other inequality

−4x+3<−6

Subtract 3 from each side

−4x+3-3<−6-3

-4x < -9

Divide by -4, remembering to flip the inequality

-4x/-4 > -9/-4

x > 2 1/4

put back together

x > 2 1/4 and x ≤4

2 1/4 < x ≤ 4

Answer:

2.25<x≤4

Step-by-step explanation:

12x−39≤9 ⇒ 12x≤ 48 ⇒ x≤4

−4x+3<−6 ⇒ -4x < -9 ⇒ x> 9/4= 2.25

2.25<x≤4

or

x= (2.25, 4]

Answer:

19

Step-by-step explanation:

To write an equation for the first situation, you need to determine which factors can be changed.  The bus will not change since you can have multiple people in one.  The ticket to the museum is per person.  This will change depending on how many people there are.

450 + 15.75x

For the second equation, you need to find how many people can go for it the cost to be equal to $40 per person.  Set the equation equal to $40 per person and solve.

450 + 15.75x = 40x

450 = 24.25x

x = 18.56

Round up to 19 since you can't 0.56 of a person.

Answer:

The solution to the system of linear equation is (0,2)

The solution to the system of linear equation is (2.-3).

Simultaneous linear equations can be defined as the two- or three-variable linear equations that can be solved together to arrive at a common solution.

Here,

3x-y=9 - - - -(1)

4x+y=5 - - - - (2)

Adding equations 1 and 2

7x = 14

x = 2

Now, we have

3(2) - y = 9

-y = 9 - 6

-y = 3

y = -3

Thus, the solution of the given simultaneous equations are x = 2 and y = -3.

Answer:

x = 14/3

Step-by-step explanation:

4(2x-3)+8(x-4)=2(2x+6)

Distribute

8x -12 +8x - 32 = 4x +12

Combine like terms

16x -44 = 4x+12

Subtract 4x

16x-4x -44 = 4x+12-4x

12x -44 =12

Add 44 to each side

12x-44+44 = 12+44

12x = 56

Divide each side by 12

12x/12 = 56/12

x = 14/3

Answer:

[tex]x=\dfrac{14}{3}[/tex]

Step-by-step explanation:

[tex]4(2x-3)+8(x-4)=2(2x+6)[/tex]

Expand parentheses:

[tex]8x-12+8x-32=4x+12[/tex]

Combine similar terms:

[tex]16x-44=4x+12[/tex]

Subtract 4x and add 44 to both sides:

[tex]12x=56[/tex]

Divide both sides by 12:

[tex]x=\dfrac{14}{3}[/tex]

Answer:

[tex][1250,1350)[/tex].

Step-by-step explanation:

It is given that a number, x, rounded to 2 significant figures is 1300.

It is possible if,

1. The value of x is greater than of equal to 1250 and less than or equal to 1300.

i.e., [tex]1250\leq x\leq 1300[/tex]     ...(1)

2. The value of x is greater than of equal to 1300 and less than 1350.

i.e., [tex]1300\leq x<1350[/tex]       ...(2)

On combining (1) and (2), we get

[tex]1250\leq x < 1350[/tex]

1350 is not included in the error interval for x.​

Interval notation is [tex][1250,1350)[/tex].

Therefore, the error interval for x is [tex][1250,1350)[/tex].

Answer:

Option 2

Step-by-step explanation:

To find the sine of F, we have to find the length of the hypotenuse which is 2√13 from the Pythagorean Theorem. Then, sinF = opposite side / hypotenuse = 4 / 2√13 = 4√13 / 26 = 2√13 / 13. Hope this helps!

Answer:

1 gallon

Step-by-step explanation:

Answer:

Independent events, 1/16

Step-by-step explanation:

What we must take into account is that they are 2 different bags, because in one bag are the black pieces and in another bag are the white feed, regardless of which piece is removed, one event has nothing to do with the other event being different bags.

Which means that they are independent events.

And the probability for each case would be 1/16, because the probability is one piece out of 16 that is in each bag.
