=(n-1)! * (n+1)

Answer:

14: 9 + 5 ℎ

15: − 1 6 + 9/ 9

Step-by-step explanation:

14 : ℎ ⋅ 5 + ( 9 )

5ℎ+ (9)

^^ Re-order terms so constants are on the left

5ℎ+ ⋅ 9 also 5 ℎ+9  then after this you would wanna re arange the terms so it would be 9 + 5 ℎ

Answer:

x = 1, x = 2

Step-by-step explanation:

Given

3x(x - 2) = x² - 4 ← distribute parenthesis on left side

3x² - 6x = x² - 4 ( subtract x² - 4 from both sides )

2x² - 6x + 4 = 0 ( divide through by 2

x² - 3x + 2 = 0 ← in standard form

Consider the factors of the constant term (+ 2) which sum to give the coefficient of the x- term (- 3)

The factors are - 1 and - 2 , since

- 1 × - 2 = + 2 and - 1 - 2 = - 3 , then

(x - 1)(x - 2) = 0 ← in factored form

Equate each factor to zero and solve for x

x - 1 = 0 ⇒ x = 1

x - 2 = 0 ⇒ x = 2

Answer:

X= 128degrees

Step-by-step explanation:

As, angles 52,38,142and X making 360 degree

52 +38+142+x=360

X=128

⇛ ∠ x° and ∠ 52° (Both are linear pairs).

A linear pair is a pair of adjacent angles formed when two lines intersect.

[tex] \bf \large \implies \: \angle \: x \: + \: \angle \: 52 \: = \: 180 \degree[/tex]

[tex]\bf \large \implies \: \angle \: x \: = \: \: 180 \degree \: - \: \angle \: 52 \:[/tex]

[tex]\bf \large \implies \: \angle \: x \: = \: 128 \degree[/tex]

Answer:

In short, 0 is the only number such that for any number x, x + 0 = x. ... So, the reason that any number to the zero power is one is because any number to the zero power is just the product of no numbers at all, which is the multiplicative identity, 1

Answer:The zero exponent rule states that any term with an exponent of zero is equal to one. This lesson will go into the rule in more detail, explaining how it works and giving some examples. There will also be a quiz to test your knowledge.

The zero exponent rule is one of the rules that will help you simplify exponents. Let's first define some terms as they relate to exponents. When you have a number or variable raised to a power, the number (or variable) is called the base, while the superscript number is called the exponent, or power.

Usually, you'll see this written with the base being a normal-size number (or letter, if you're working with a variable). The exponent will be in a slightly smaller font, raised a little up above and to the right of the base. However, in some formats, like this one, you'll see the base, a mark called a caret that looks like an inverted V, and then the exponent. So if you have a base of 2 and an exponent of 3, we'll write that out here as 2^3 = 8.

Now that you know the terms, let's go back to the zero exponent rule. The zero exponent rule basically says that any base with an exponent of zero is equal to one. For example:

x^0 = 1

Answer:

A

Step-by-step explanation:

Let us start with B = 90

That would mean that each of the other 2 angles must add to 90 which makes each of them 45.

But the question doesn't allow that. B has to be greater than 90 which means that the other two angles must be less that 45 each.

the only answer that does that is A

Answer: y= 3x+2

Step-by-step explanation:

because....

The slope-intercept form is y= mx +b, where m is the slope and b is the y-intercept.Use the slope 3 and a given point (1,5) to substitute for  and  in the point-slope form .

y-(5)= 3*(x-(1))

After simplifying it,

the equation is going to be y= 3x+2.

Answer:

A

Step-by-step explanation:

The vertex is at (2,1) The two is the important feature to start with. That means that the point is 2 away from the y axis. That goes to the left to get to the y axis.

The get the mirror image of that 2, you have to go two to the right to get to the point that mirrors (0,4). The y value has to be the same as the y intercept. So x must be 4 and y needs to be 4.

The answer is (4,4)

In case you are interested, the graph (given below) is y = 0.75 (x - 2)^2 + 1

The y intercept is 0,4 and the vertex is 2,1

Answer:

7 is divided by 15 =0•4666666667

Answer:

ab=9

Step-by-step explanation:

AB=BC

2X+31=20+X

X=-11

ab= 20+(-11)

= 9

bc= 2(-11) +31

=9

ab+bc= ac

9+9=18

Answer:

691 251/256

Step-by-step explanation:

So basically exponents is how much time you time the same number

First on the top is 2 exponent 4. that is 2x2x2x2=16

Second is 3 exponent 3. 3x3x3=27

Third is 9 exponent 7. 9x9x9x9x9x9x9=4782969

Fourth is 4 exponent 6. 4x4x4x4x4x4=4096.

All together is 16/27x4782969/4096=691 251/256

Answer:

y = 2x+4

Step-by-step explanation:

The y intercept is 4

We can find the slope

m = ( y2-y1)/(x2-x1)

   = (4-10)/(0-3)

   = -6/-3

   = 2

The slope intercept form is

y = mx+b where m is the slope and b is the y intercept

y = 2x+4

Answer:

90 and 90

Step-by-step explanation:

If they are perpendicular it means they cross at a 90 degree angle so since both L and M are perpendicular to N both the answers would be 90

Hope This Helps :)

Answer:

I would say 90 degrees for both, simply because it's not perpendicular if the angle isn't 90 degrees.

Answer:

y=4

Step-by-step explanation:

it has only one solution.

Answer:

$800

Step-by-step explanation:

Let x represent the original price of the speakers.

$34 more than one quarter of the original price can be represented by 1/4x + 34.

Set this equal to 234, the price he paid, to create an equation.

1/4x + 34 = 234 is the equation for the problem.

Solve for x in the equation:

1/4x + 34 = 234

1/4x = 200

x = 800

So, the original price of the speakers was $800

Answer:

1) 2400MB

2) 3 minutes

Step-by-step explanation:

1) 600 MB/Min * 4 Min = 2400MB

2) at 800 MB/Min a 2400MB file will require 2400MB/800MB/Min

  2400/800 = 3Min

Answer:

x = 3

Step-by-step explanation:

Since this is a right triangle, we can use trig functions

tan theta = opp side / adj side

tan 30 = sqrt(3) / x

x tan 30 = sqrt(3)

x = sqrt(3) / tan 30

x =sqrt(3) / (1 / sqrt(3))

x = sqrt(3) * sqrt(3)

x = 3

answer for the question is 87

Hey there!

Mode is basically the number(s) in a data plot you see MORE THAN once

• 18 appeared four times (this could be a possible answer)

• 17 appeared four times (this could be a possible answer)

• 19 appeared one time (this can’t be your answer)

• 20 appeared two times (this could be a possible answer)

Possible answers: 17,18, & 20

Since 17 & 18 appeared the MOST in the data plot those numbers could be your mode in your given data plot

Answer: 17 & 18

Good luck on your assignment and enjoy your day!

Step-by-step explanation:

A line parallel to a side of the triangle and it intersects the other two sides, then it divides those sides proportionally, that is

[tex]\frac{a}{b}[/tex] = [tex]\frac{d}{c}[/tex] → C

Answer:

9.4cm

Step-by-step explanation:

by pythagoras theorem,

a^2 + b^2 = c^2

5^2 + 8^2 = c^2

c^2 = 89

c = √89 = 9.433981 ≈ 9.4

Answer:

First find the coordinates of the vertices. A=(-8,8), B=(-8,3) and C=(-4, 4). Next apply transformation, A'=(2, 2), B=(2, - 3) and C=(6, - 2). Next map this and join them to get the required triangle

Answer:

K = (3,3)

After a reflection across the x axis (Vertical reflection), the coordinate becomes (3, -3)

Let me know if this helps!

Answer

(3, -3)

I'm pretty sure that's the answer, because reflecting the shape along the x-axis would mean having to reflect it horizontally. Once you do that, you'll find that the point K would meet its destination at (3, -3).

Answer: x = -3

[tex]2x+6=0\\\\2x=-6\\\\x=\frac{-6}{2} =-3[/tex]

Answer:

x= -3

Step-by-step explanation:

Solve the equation:

2x +6 = 0

We have isolate 'x'.

First subtract 6 from both sides

2x = 0-6

2x = -6

Divide each side by 2

x = -6/2

x = -3
