If 6x + 4 = 11x - 21, what is the value of x?

Answers

Answer 1

Answer:

x = 5

Step-by-step explanation:

11x - 6x = 4 + 21

5x = 25 (÷5)

x = 5

Answer 2
X=5

Explanation: 6x + 4 = 11x - 21
1). Subtract 4 from both sides and you will get 6x = 11x -25.
2). Subtract 11x from both sides and you should get -5x = -25.
3). Divide the -5 with -25 to get x alone and you should get X=5!

Check your work:
6(5) + 4 = 34 & 11(5) - 21 = 34
34=34.

This is the table of values of a function. Write the output when the input is n.

Input= 4 6 9 n
Output= 2 4 7 ?

Answers

Answer:

n-2

Step-by-step explanation:

1. Find what has been done to the input value to give the output value. Here, we can see that each input value is two more than each output value, so two has been subtracted from each input value to give the output. This means that the rule for this function is: take the input value and subtract two.

2. Express this in terms of n. We can then express this in terms of n (using n to show the rule that we have found). Since n is the input value we have, to find the output when the input is n, we subtract two from n. This gives us our answer of n-2.

Answer:

ik that angle one would be the same as 3 and 2 and 4 are also the same so if u find an answer for 2 or 4 they would be the same but is there like a total of the entire thing

Answer:

Angle 1 = 72 degrees

Angle 2 = 110 degrees

Angle 4 = 110 degrees

Step-by-step explanation:

Use angle rules.

Angle 2 + angle 3 = 180, because they supplementary angles.  Therefore, to find angle 2, you can do 180 - 72 = 110 degrees.

Angle 1 and angle 3 are vertical angles, meaning they are equal.  Thus, angle 1 = 72 degrees.

Angle 2 and 4 are vertical angles, meaning they are equal.  Thus, angle 4 = 110 degrees.

I used the pythagorean theorem on BAC triangle

If you have any questions about the way I solved it, don't hesitate to ask me in the comments below ;)

The length of BC is 15 units.

In the right triangle ABC.

we have AC = 8 units and AB = 17 units.

We need to find the length of BC using the Pythagorean theorem.

What is the Pythagorean theorem?

It states that in a right-angled triangle the square of the hypotenuse is equal to the sum of the squares of the other two sides.

In the given right-angle triangle ABC.

We have,

AB = hypotenuse and the other two sides are AC and BC.

Applying the Pythagorean theorem.

We get,

[tex]AB^{2} = AC^2 +BC^2[/tex]

Now substitute AC = 8 and AB = 17.

[tex]17^2=8^2+BC^2\\289=64+BC^2\\BC^2=289-64\\BC^2=225\\BC=\sqrt{225}\\ BC=15 ~units.[/tex]

Thus, we have the length of BC as 15 units.

A square has an area of 9yd^2. What is the length of each side?

Answers

Answer: The side length is 3 yards.

Step-by-step explanation:

To find the area of a square, you have to square one of it's side lengths since they all share the same length.  Since we know the area, and we need to find the side length so we just need to find the square root of the area.

[tex]\sqrt{9}[/tex] = 3    

The side length is 3 yards.

The length of each side of a square is, 3 yards.

What is mean by Rectangle?

A rectangle is a two dimension figure with 4 sides, 4 corners and 4 right angles. The opposite sides of the rectangle are equal and parallel to each other.

We have to given that;

⇒ An area of square = 9 yards²

Now, We know that;

⇒ Area of square = Side²

Let the side of square = a

So, We get;

⇒ a² = 9

⇒ a = √ 9

⇒ a = 3 yards
