Answer:

Not arithmetic and no common difference.

Step-by-step explanation:

Arithmetic sequence is a sequence of numbers increasing or decreasing in a constant form. That is where the common difference come.

To get the common difference to determine if it is arithmetic, you subtract the values like this: n₂ - n₁ = n₃ - n₂ = n₄ - n₃ and so on.

So,

-7 - (-3) = -4

-10 - (-7) = -3

-14 - (-10) = -4

As you can see, there is one set of numbers that result to -3 while the others are -4. They are not arithmetic and do not have a common difference.

Answer:

Not an arithmetic sequence

Step-by-step explanation:

For the sequence to be arithmetic there must be a common difference between consecutive terms.

- 7 - (- 3) = - 7 + 3 = - 4

- 10 - (- 7) = - 10 + 7 = - 3

- 14 - (- 10) = - 14 + 10 = - 4

The differences are not common , hence not an arithmetic sequence

F(x)=x^2 horizontal shift of 3 vertical shift of -2 reflected over the x-axis. Write the equation

Cerrena [4.2K]

$f(x) = -(x-3)^{2} -2$ is the required function.

Step-by-step explanation:

We have to find the transformation after the horizontal and vertical shifts and then reflection over the x-axis for the given function.

$f(x) = x^{2}$

If there is a horizontal shift of 3, then the function becomes, $f(x) = (x-3)^{2}$

If there is a vertical shift of -2, then the function becomes, $f(x) = (x-3)^{2} -2$

The function is reflected over the x- axis then the function becomes,

$f(x) = -(x-3)^{2} -2$

It is know that BD is an angle bisector with...

Georgia [21]

Answer: x = 10 or x = -6

Step-by-step explanation: If ray BD bisects <ABC, then <ABD ≅ <DBC.

So we can setup the equation x² - 4x = 60.

To solve this polynomial equation, we need to set it equal to 0.

So we subtract 60 from both sides to get x² - 4x - 60 = 0.

On the left, we have a trinomial in a special form that can

be factored as the product of two binomials.

In the first position of each binomial,

we have the factors of the x squared term, x and x.

In the second position, we're looking for the factors

of -60 that add to -4 which are -10 and +6.

So we have (x - 10)(x + 6) = 0.

Whenever two terms are multiplied together to equal 0,

this means that either one or the other must equal 0.

So if (x - 10)(x + 6) = 0, then either x - 10 = 0 or x + 6 = 0.

Solving each equation from here, we find that x = 10 or x = -6.

If you plug both values of x in for the measures of the angles,

you will find out that both of these give us true statements.
