Step-by-step explanation:your gay

Your answer would be the second one.

We know that adding [tex]\frac{1}{2}[/tex] to x gives us 4, as that's provided by the question.

So [tex]4=x+\frac{1}{2}[/tex]. Now, to find x, simply subtract [tex]\frac{1}{2}[/tex] from 4 to give us x, which gives us [tex]3\frac{1}{2}[/tex].

Answer:

k = -10

Step-by-step explanation:

1) Because of the division of the left side of the equation by 2, multiply both sides of the equation by 2, which means you now have :

-8 - 3k = 22

2) Now, add eight to both sides. Your equation now looks like this:

-8 + 8 - 3k = 22 + 8

3) Simplify.

-3k = 30

4) You now have k = -10

The ratio of pencils to all the item on the desk is 1 : 10

According to Gary,

    Number of pencils on the desk = 4

    Number of markers on the desk = 12

   Number of crayons on the desk = 24

Total number of item son the desk = 4 + 12+ 24

                                                             = 40

The ratio of pencils to all the item is given as = (number of pencils)/(total number of items)

                                                                                = 4/40

                                                                                = 1/10

                       Which in ratio can be written as 1 : 10

Thus the ratio of pencils to all the item is 1 : 10

Answer:

Distance: 4√41

Midpoint: (2, 3)

Step-by-step explanation:

A: (-6, 13) B: (10, -7)

    (x₁, y₁)       (x₂, y₂)

d = √(x₂ - x₁)² + (y₂ - y₁)²

d = √(10 - (-6))² + (-7 - 13)²

d = √(16)² + (-20)²

d = √256 + 400

2) Angle 3 is Vertically opposite to Angle 1

So they are the same Angle

3) Angle 4 is Vertically opposite to Angle 2

So they are the same Angle

4) Angle 5 is corresponding to Angle 1

So they are the same angle

5) Angle 6 is corresponding to Angle 2

So they are the same angle

6) Angle 7 is corresponding to Angle 3

So they are the same angle

The required value of constant of variation, k does not exist for which x and y vary directly..

What is the constant of proportion?

A constant of proportion is illustrated as the ratio which relates two given quantities with each other in the relationship of proportion. Constant of proportion is also called constant variation, rate of change, and constant ratio.

Solving for the value of constant of variation

When a quantity varies directly with others, then we have a relation, y = kx, where k is the constant of the proportion      —-- 1

Given relation is  y + 3 = -3 x

y = -3 x - 3

y = -3(x + 1)

Comparing with equation 1, we get that y does not vary directly for any value of k.

Hence, the required value of constant of variation is does not exist.

The compound inequality in this problem is represented by:

y > -(x + 2)² + 6.

The equation of a quadratic function, of vertex (h,k), is given by:

y = a(x - h)² + k

In which a is the leading coefficient.

For this problem, the vertex is at (-2,6), hence:

h = -2, k = 6.

y = a(x + 2)² + 6.

When x = 0, y = 2, hence we use it to find a as follows:

2 = 4a + 6

a = -1.

Hence:

y = -(x + 2)² + 6.

The inequality is the interior of the parabola, hence values greater, and the parabola is dashed, hence it is an open interval and the inequality is given by:

y > -(x + 2)² + 6.

an=a1+d(n−1)  is the explicit and a recursive formula for each sequence .

See the pattern

-32-(-20) = -12

-20-(-8) = -12

-8-4 = -12

By this the explicit and a recursive formula for each sequence is  an=a1+d(n−1).

An ordered group of numbers with a shared difference between each succeeding word is known as an arithmetic sequence. For instance, the common difference in the arithmetic series 3, 9, 15, 21, and 27 is 6.

Arithmetic sequences are sequences containing these patterns. The distance between succeeding terms in an arithmetic series is always the same. The difference between consecutive words is always two, hence the sequence 3, 5, 7, 9... is arithmetic.

An explicit formula that states a = d (n - 1) + c, where d is the common difference between succeeding words, and c = a1, can be used to establish an arithmetic sequence.

The numerical length of BD is 20.

We have a Line Segment BD and a point C on it.

We have to determine the numerical length of BD.

A line segment is a piece or part of a line having two endpoints. Unlike a line, a line segment has a definite length.

According to question, we have -

BD = 5x

BC = 4x

CD = 4

Now,

BD = BC + CD

5x = 4x + 4

x = 4

Therefore - BD = 5x = 5 x 4 = 20

Sn = a(1 - rⁿ)/(1 - r) is the formula for the sum of a finite number of terms in a geometric series, where is the number of terms, is the first term, and is the common ratio.

The sum of the finite geometric series, Σ⁴ n=1 (2/3)ⁿ⁻¹ be 2.407.

The equation be Sn = a(1 - rⁿ)/(1 - r), where s is the total, a1 is the series's first term, and r is the common ratio, is a general formula for calculating the sum of an finite geometric series. The formula a2/a1, where a2 is the second term in the series and a1 is the first term in the series, can be used to determine the common ratio.

Let the series be Σ⁴ n=1 (2/3)ⁿ⁻¹

Σ⁴ n=1 (2/3)ⁿ⁻¹ = (2/3)¹⁻¹ + (2/3)²⁻¹ + (2/3)³⁻¹ + (2/3)⁴⁻¹

= 1 + (2/3) + (2/3)² + (2/3)³

= 1 + (2/3) +(4/9) +(8/27)

Where, the first term is a = 1

common ratio be r = 2/3

n th term be n = 4

Let the equation be Sn = a(1 - rⁿ)/(1 - r)

substitute the values in the above equation, we get

S4 = 1(1 - (2/3)⁴)/(1 - (2/3))

S4 = 1(1 - (16/81)⁴)/(1/3)

S4 = (65/81) × 3

S4 = (65/27) = 2.407

Therefore, the sum of the finite geometric series, Σ⁴ n=1 (2/3)ⁿ⁻¹ is 2.407.

We have two polynomials 9(x + 2)(2x - 1) and 3(x + 2).

Since, we have to find the least common multiple of 9(x + 2)(2x -1) and 3(x+2).

As we know that, the least common multiple, lowest common multiple, or smallest common multiple of two integers a and b, usually denoted by lcm(a, b), is the smallest positive integer that is divisible by both a and b. Since division of integers by zero is undefined, this definition has meaning only if a and b are both different from zero.

From the definition of least common multiple, we can say that the least common multiple of 9 and 3 is 3 and (x +2)(2x -1) and (x + 2) is (x + 2).
