WILL GIVE BRAINLIEST AND 20 POINTS! Which function is the inverse of f(x) = -5x -4?

Answer:

2x(3x + 2)

Step-by-step explanation:

Answer

102

Step-by-step explanation:

X means 3 not times, lots of people mess that up sometimes. Anyways, do 8+3 which equals 11. 8+3=11. So next what you do is you do 11 + 16 which is 27,

equations:

8+3=11

11+16=27

21/1=27

27/4= 6.75

6 x 3= 27

27 + 72 + 3= 102

Then go back to the beginning and do 1/4. If this confuses let me fix it.

now divide it with 4. Look at the equations list. Okay now do 6.72/4x. MAKE SURE TO MULTIPLY DON'T DIVIDE! You multiply 6 and 4 then you add 72 and three! Then you should end up with 102! I hope this worked message me back if it did :)

-The final answer is [tex]9x + 6[/tex] .

Step-by-step explanation:

Simplify the following equation:

[tex]2(x - 4) + 7(x + 2)[/tex]

-Use Distributive Property:

[tex]2(x - 4) + 7(x + 2)[/tex]

[tex]2x - 8 + 7x + 14[/tex]

-Combine [tex]2x[/tex] and [tex]7x[/tex] together:

[tex]2x - 8 + 7x + 14[/tex]

[tex]9x - 8 + 14[/tex]

Add [tex]-8[/tex] and [tex]14[/tex] together:

[tex]9x - 8 + 14[/tex]

[tex]9x + 6[/tex]

So, the final answer is [tex]9x + 6[/tex] .

Answer:

B

Step-by-step explanation:

Because ∠EDF and ∠BDC are vertical angles, ∠D = 9x. Since ∠ABD and ∠BDC are supplementary, our answer is 2x + 105° + 9x = 180° or B.

Answer:

B

Step-by-step explanation:

∠ BDC = 9x ( vertical angles )

∠ ABD and ∠ BDC are supplementary , thus

∠ ABD + ∠ BDC = 180 , substitute values

2x + 105 + 9x = 180 → B

Answer:

x² + y² = 72

Step-by-step explanation:

The equation of a circle centred at the origin is

x² + y² = r² ( r is the radius )

The radius is the distance from the centre to a point on the circle.

Use the distance formula to calculate r

r = √ (x₂ - x₁ )² + (y₂ - y₁ )²

with (x₁, y₁ ) = (0, 0) and (x₂, y₂ ) = (6, 6)

r = [tex]\sqrt{(6-0)^2+(6-0)^2}[/tex]

  = [tex]\sqrt{6^2+6^2}[/tex]

  = [tex]\sqrt{36+36}[/tex]

  = [tex]\sqrt{72}[/tex]

Thus

x² + y² = ([tex]\sqrt{72}[/tex] )² , that is

x² + y² = 72 ← equation of circle

Answer:

15.94490514

Step-by-step explanation:

First, work out the average, or arithmetic mean, of the numbers:

Count: 5(How many numbers)

Sum: 357(All the numbers added up)

Mean: 71.4(Arithmetic mean = Sum / Count)

Then, take each number, subtract the mean and square the result:

Differences:

4.6, -26.4, -7.4, 8.6, 20.6

(Every Number minus Mean)

Differences^2:

21.16, 696.96, 54.76, 73.96, 424.36

(Square of each difference)

Now calculate the Variance:

Sum of Differences2:1271.2(Add up the Squared Differences)

Variance:254.24(Sum of Differences2 / Count)

Lastly, take the square root of the Variance:

Standard Deviation:15.94490514 (The square root of the Variance)

Answer:

Distance around the pool = 162.8 feet

Area of the pool = 957 square feet

Step-by-step explanation:

Distance around the swimming pool = Perimeter of the pool

Perimeter of the pool which is a composite figure will be,

= Circumference of the semicircle + Sum of three sides of the pool

= πr + 2×(length of the pool) + width of the pool

= 3.14×(10) + 2×40 + 20

= 62.8 + 80 + 20

= 162.8 ft

Area of the pool = Area of the semicircle + Area of the rectangular pool

                           = [tex]\frac{1}{2}(\pi)(r)^{2}+(\text{length}\times \text{Width})[/tex]

                           = [tex]\frac{1}{2}(3.14)(10)^2+(40\times 20)[/tex]

                           = 157 + 800

                           = 957 square feet

[tex]x = 67.5 \\ solution \\ x + 3x + 90 = 360(sum \: of \: complete \: turn) \\ or \: 4x + 90 = 360 \\ or \: 4x = 360 - 90 \\ or \: 4x = 270 \\ or \: x = \frac{270}{4} \\ x = 67.5 \\ hope \: it \: helps[/tex]

Answer: x = 67.5°

Step-by-step explanation:

Is this for area or the magnitude of the angle? Ill solve for the angle. A circle has a total degree of 360. And they give us the right angle of 90°.

So the equation we have here is 90 + 3x + x = 360. Subtract 90 from both sides to get 3x + x = 270. Combine the like terms to get 4x = 270. Now just divide each side by 4 to get 67.5°

Answer:

76.58 feet.

Step-by-step explanation:

A yard is 3 feet. Change each value to feet. So then we have 2 pieces of rope that are each 48 feet in length, 1 piece of rope that is 4.17 feet in length, and 1 piece of rope that is 123.25 feet in length. Add these all together. 223.42 is what you get. Subtract this from 300. You get 76.58.

Answer:

132.25 feet

Step-by-step explanation:

total rope they have now= (2x16)+(1x12.5)+(1x123.25)= 167.75

additional rope needed= 300-167.75= 132.25

There are 12 marbles in the bag

9 marbles are not blue

P(not blue) = marbles that are not blue / total marbles

                   = 9/12 = 3/4

Answer:

D

Step-by-step explanation:

1/4 x -36 = -9

1/4 x 4/3 = 1/3

1/4 x 12 = 3

But...

1/4 x 0.444444... = 0.111111...

So A is the answer

√12  produces an irrational number when multiplied by 1/4

A real number that cannot be expressed as a straightforward fraction is referred to as an irrational number. It cannot be described using a ratio. When p and q are integers and q is not equal to 0, N is not equal to p/q if N is irrational.

Given Four numbers to find the number that will produce an irrational number after dividing by 4. We will check them one by one:

For A, 0.4444:

=> 0.444

After multiplying by 1/4

=> 0.1111111

That can also write as 1/9(Not an irrational number)

For C, -√36:

=> -√36

After multiplying by 1/4

=>-√9/4

That can also write as 3/2(Not an irrational number)

For D, 4/3:

=> 4/3

After multiplying by 1/4

=> 1/3

That can also write as 1/3(Not an irrational number)

For B. √12:

=> √12

After multiplying by 1/4

=> √12/4

=>√(3/4)

That can also writes as √(3/4)(yes, an irrational number)

Therefore, The irrational number in the given option is B √12

Answer: -$13.47 per hour

Step-by-step explanation:

Hi, to answer this question we have to write an expression:

The total amount earned by the employee will be equal to the product of the number of hours he worked (36) and the amount paid per hour (9.25) ; plus the product of the amount paid for every 20 transformers assembled (8) and the number of transformers assembled (380)divided by 20 :

9.25 (36) + 8 (380/20) =  

Solving:

333+ 8 (19) =

333+152 = $485

Answer:

40

Step-by-step explanation:

A quarter of 1600: 400

A tenth of 400:40

The value of 10th of a quarter of 1600 is 40.

A quarter of the number is 1/4 times of the number i.e. times of the number.

Quarter of x= (1/4)*x= 0.25 * x

Given in the question that we have to calculate 10th of a quarter of 1600.

Before that we have  to first calculate a quarter of 1600 which is calculated by using the above formula

quarter of 1600= (1/4)*1600= 0.25* 1600= 400

Now we have to calculate 10th of a quarter of 1600 i.e. 10th of 400.

10th of 400= (1/10) * 400= 40

Therefore the value of 10th of a quarter of 1600 is 40.
