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.

Answer:

  (x, y, z) = (2, 1, -5)

Step-by-step explanation:

There are numerous equation solvers available on the web. The attached result is from one of them.

__

You may find it easier to solve these by hand if you eliminate fractions.

2x -y +z = -2x +3y -z = 10x +0y +2z = -8

The first step is to look to see what you have, then formulate a strategy for getting a solution. Because the equations containing y have opposite coefficients, one of which is -1, we choose to use those to eliminate y. Immediately, we will have two equations in x and z.

If  you multiply the first equation by 3 and add that to the second, then you will eliminate y. The third equation already has y eliminated, so you will then have two equations in x and z.

  3(2x -y +z) +(x +3y -z) = 3(-2) +(10)

  6x -3y +3z +x +3y -z = -6 +10

  7x +2z = 4 . . . . [eq4]

Subtracting the third equation from this eliminates z, so you have ...

  (7x +2z) -(x +2z) = (4) -(-8)

  6x = 12

  x = 2

Substituting into the third equation gives ...

  2 +2z = -8

  2z = -10

  z = -5

Then using the first equation, you have ...

  y = 2x +z +2 = 2(2) +(-5) +2 = 1

(x, y, z) = (2, 1, -5)

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) The y-intercept for f(x) is greater than the y-intercept for g(x).
B) The y-intercept for both functions is (0,0).
C) The y-intercept for g(x) is greater than the y-intercept for f(x)
D) The y-intercept for both functions is (0, 2).​

Answers

Answer:

Should be C

Step-by-step explanation:

The y-intercept for f(x) is greater than the y-intercept for g(x). Therefore, option A is the correct answer.

What is a y-intercept?

In Maths, an intercept is a point on the y-axis, through which the slope of the line passes. It is the y-coordinate of a point where a straight line or a curve intersects the y-axis. This is represented when we write the equation for a line, y = mx+c, where m is slope and c is the y-intercept.

From the table, we have the coordinates (-2, 0) and (-1, 1).

Here, slope (m)=(1-0)/(-1+2)

m=1

Substitute m=1 and (x, y)=(-2, 0) in y=mx+c, we get

0=1(-2)+c

c=2

From the graph y-intercept is c=1

Therefore, option A is the correct answer.

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
