Simplify expression and can you explain how

Answer:

d. Subtract x from both sides.

Answer:

80 Ft²

Step-by-step explanation:

Area= length x width

length= 10 feet

width= 8 feet

A= 10 × 8

A= 80 Ft²

squared because it's feet multiplied by feet

Ft × Ft= Ft²

A functional rule is the relationship between an input or domain and an output or scope.

The given function is as follows:

x: -6, -3, 0, 3, 6

y: 5, -1, -7, -13, -19

A functional rule is the relationship between an input or domain and an output or scope. A relation is a function only if it has a value within each domain value. Functions are written like where is the input value. The general form of the function is:

A formula, rule, or law that defines the relationship between one variable (the independent variable) and another (the dependent variable). Functions are ubiquitous in mathematics and essential in the natural sciences for formulating physical relationships.

Let the given function be y = -2x - 7.

Where, x = -6

substitute the values in the above equation, we get

⇒ y = -2(-6) - 7

⇒ y = 5

Let the value of x = -3

substitute the values in the above equation, we get

⇒ y = -2(-3) - 7

⇒ y = -1

Put, x = 0

substitute the values in the above equation, we get

⇒ y = -2(0) - 7

⇒ y = -7

Put, x = 3

substitute the values in the above equation, we get

⇒ y = -2(3) - 7

⇒ y = -6 - 7 = -13

Put, x = 6

substitute the values in the above equation, we get

⇒ y = -2(6) - 7

⇒ y = -19

The given function is as follows:

x: -6, -3, 0, 3, 6

y: 5, -1, -7, -13, -19

Answer: [tex]\angle 6[/tex]

Step-by-step explanation:

Assuming TURS is a rectangle, [tex]\angle 5 \cong \angle 6[/tex] by the alternate interior angles theorem.

Answer:

Step-by-step explanation:

area of rectangle=l*b

Answer:

54061 in³

Step-by-step explanation:

Using proportion

Perimeter of smaller pyramid/ Perimeter of Larger pyramid = volume of smaller pyramid/ volume of Larger pyramid

30/36 = x/64873

Cross Mulitiply

36 × x = 64873 × 30

x = 64873 × 30/36

x = 54060.833333 in³

Approximately = 54061 in³

Therefore, the volume of the smaller pyramid is 54061 in³

Answer:

y_2 is 8 units

Step-by-step explanation:

Given that

The distance between the point is 13 units

x_1 is 5

y_1 is 3

x_2 is -7

We need to find out the y_2

So, the following formula should be used

[tex]d = \sqrt({x_2 - x_1})^2 + (y_2 - y_1)^2\\\\13 = \sqrt({-7-5})^2 + (y_2 - 3)^2\\\\169 = 144 + (y_2)^2 + (-3)^2 - 2(y_2) (-3)\\\\25 = (y_2)^2 + 9 - 6y_2\\\\16 = (y_2)^2 -6y_2\\\\(y_2)^2 -6y_2 - 16 = 0\\\\(y_2)^2 - 8y_2 + 2y_2 - 16 = 0\\\\y_2 (y_2 - 8) + 2(y_2 - 8) = 0\\\\y_2 = 8[/tex]

hence, y_2 is 8 units

Answer:

x = -48

Step-by-step explanation:

-4(7.5x - 8) = -5(6.3x + 8)

-30x + 32 = -31.5x - 40

-30x + 31.5x = -40 - 32

1.5x = -72

x = -72/(1.5)

x = -48

By using the relative frequency, we can expect to not roll a "6" in 11 rolls.

We know that in a total of 72 rolls, the outcome is "6" 21 times.

Then the relative frequency is:

F = 21/72 = 0.292

Then we can expect that in N rolls, we will get (0.292)*N times a "6".

So the number of times that we will not get a 6, is:

(1 - 0.292)*N

In this case is N = 15, then we get:

(1 - 0.292)*15 = 10.62

Rounding to the next whole number we get 11, this means that we can expect to not roll a "6" in 11 rolls.

To find:

The simplified form of the given expression.

Solution:

We have,

[tex]\log_5(36)-\log_5(9)[/tex]

It can be written as:

[tex]\log_5(36)-\log_5(9)=\log_5\dfrac{36}{9}[/tex]              [tex][\because \log_m\dfrac{a}{b}=\log_ma-\log_m b][/tex]

Answer:

[tex]a_{n}[/tex] = - 2 [tex](4)^{n-1}[/tex]

Step-by-step explanation:

There is a common ratio between consecutive terms , that is

r = - 8 ÷ - 2 = - 32 ÷ - 8 = - 128 ÷ - 32 = 4

This indicates the sequence is geometric with nth term

[tex]a_{n}[/tex] = a₁ [tex](r)^{n-1}[/tex]

where a₁ is the first term and r the common ratio

Here a₁ = - 2 and r = 4 , then explicit formula is

[tex]a_{n}[/tex] = - 2 [tex](4)^{n-1}[/tex]

Answer:

Step-by-step explanation:

Given the expression

b|3a – 81 – 3/2 – 2a

If a = -4, b = 1/2

Substitute

(1/2)/3(-4) - 81 - 3/2 - 2(-4)

1/2 * 1/-12 - 81 - 3/2 + 8

= -1/24 - 81 + 8 - 3/2

= -1/24 - 3/2 - 73

= -1-36-1,752/24

= -1,789/24

Answer:

12x - 29 + 4x + 1 = 180

Step-by-step explanation:

(12x - 29) and (4x + 1) are same- side interior angles and sum to 180° , then

12x - 29 + 4x + 1 = 180 ← is the equation to solve for x

16x - 28 = 180 ( add 28 to both sides )

16x = 208 ( divide both sides by 16 )

x = 13

Step-by-step explanation:

The sea level serves as a reference point and may be used to describe objacetsvir positions above or below it. Therefore, the sea level is regarded as a zero point or level. Hence, objects below are describes to be at a negative distance while those above are assigned the positive sign. Hence, for a position which is 12 km below sea level, then the object is said to be at a distance of - 12 km (below sea level takes the negative sign.)
