Determine if each sequence is an arithmetic sequence. If yes, find the common difference.
1. 10,12,15,19,…
2. If there is, what is the common difference?

Answers

Answer: Yes, add one more each time you add

Step-by-step explanation:

No, the sequence is not arithmetic.

The difference between 10 and 12 is 2.
The difference between 12 and 15 is 3.
The numbers increase by different amounts each time, not by a constant amount, thus the sequence is not arithmetic.

Eliza claims that the two squares are congruent. Which statement could be used to prove Eliza's claim?

A) Any two squares are congruent since all squares have angles of 90 degrees

B) The two squares are congruent since a translation carries one square onto the other.

C) Any two squares are congruent since all four sides of any square are congruent.

D) The two squares are congruent since a rotation about the origin carries one square onto the other.

Answers

Answer:

A

Step-by-step explanation:

I Hope this helps you out!

Eliza claims that the two squares are congruent. The statement that could be used to prove Eliza's claim can be found in Option A.

Any two squares are congruent since all squares have angles of 90 degrees.

A figure is said to be congruent if they have similar angles and the position of each shape corresponds to each other.

From the given figure attached to the question, we can see that the two shapes in the figure are squares, and they are located at 2 units each from the origin. The angles of each shape are 90° to the horizontal line and they are perpendicular to each other.

 

The two squares may not be congruent since not only translation carries one square onto the other, from the figure in the question, it may be a reflection and not only translation.

Also, only the sides of a shape cannot be used as a determining factor to determine if a shape is congruent or not.

Therefore, we can conclude that any two squares are congruent since all squares have angles of 90 degrees.

A linear regression equation is computed for a sample of n = 13 pairs of X and Y scores. For the analysis of regression testing the significance of the equation, what are the df values for the F-ratio?

Answers

Answer:

The degrees of freedom are

                         ν₁ = n₁ -1 = 13 -1 = 12

                          ν₂= n₂-1 = 13 -1 =12

Step-by-step explanation:

Step(i):-

Given size 'n' = 13

size of sample of X score     n₁ = 13

size of sample of Y score     n₂ = 13

The degrees of freedom are

                         ν₁ = n₁ -1 = 13 -1 = 12

Answers

Answer:

x = -1, y = -2

Step-by-step explanation:

-3x-4y=11

y=2x

Plug in 2x for y:

-3x-4(2x)=11

-3x-8x = 11

-11x = 11

x =-1

Plug in x in y = 2x

Polygon MNP shown on the coordinate planeA dilation centered about the origin will be performed on the polygon with vertices M(- 18, 12) forall(8,10),8(-6,8) and Q(- 8, - 8)

Answers

Answer:

N'(4, 5)

Step-by-step explanation:

The correct question is attached.

Transformation is the movement of a point from its initial location to a new location. Types of transformation are reflection, rotation, dilation and translation.

Dilation is a transformation that changes the size of a figure (i.e. it increases or reduces the size).

If a point A(x, y) is dilated by a factor k, the new point is at A'(kx, ky).

The location of the polygon vertex is at M(-16, 12), N(8, 10), P(-6, 8) and Q(-8, -8).

After dilation, the new location of M is at M'(-8, 6)

M(-16, 12) ⇒ M'(-8, 6)

M(-16, 12) ⇒ M'[1/2(-16), 1/2(12)]

Hence the dilation factor is 1/2. This means that the new vertex is at:

N'(4, 5), P'(-3, 4) and Q'(-4, -4).

Which of the following is a solution to the system? Show your work.

3x+2y=-3

3x-y=6

Group of answer choices

(-1, 0)

(1, -3)

(2, 0)

LaTeX: (0,-\frac{3}{2})

Answers

Answer:

(1, -3) is a solution to the system of equations ⇒ B

Step-by-step explanation:

Let us solve the system of equations

3x + 2y = -3 ⇒ (1)

3x - y = 6 ⇒ (2)

→ Subtract equation (2) from equation (1)

∵ (3x - 3x) + (2y - -y) = (-3 - 6)

∴ (0) + (2y + y) = (-9)

∴ 3y = -9

→ Divide both sides by 3 to find y

y = -3

→ Substitute the value of y in equation (2) to find x

∵ 3x - (-3) = 6

∴ 3x + 3 = 6

→ Subtract 3 from both sides

∵ 3x + 3 - 3 = 6 - 3

∴ 3x = 3

→ Divide both sides by 3 to find x

x = 1

To check the answer substitute the values of x any in each equation if the two sides of the equation are equal, then the solution is right

∵ 3x + 2y = -3

∵ 3(1) + 2(-3) = -3

∴ 3 - 6 = -3

-3 = -3

→ The two sides of the equation are equal

∵ 3x - y = 6

∵ 3(1) - (-3) = 6

∴ 3 + 3 = 6

6 = 6

→ The two sides of the equation are equal

∴ The solution satisfies the two equations

(1, -3) is a solution to the system

Step-by-step explanation:

Answer: y = 50; x = 34

ABCD is a  quadrilateral inscribed in the circle

=> ∠ABD = ∠ACD

⇔ x = 34°

and ∠ADB = ∠ACB

we also have:

∠DCE + ∠ DCB = 180°

⇔ 96° + x + ∠ACB = 180°

⇔ ∠ACB = 180 - 96 - x = 180 - 96 - 34 = 50

because ∠ADB = ∠ACB => y = 50°
