find the 7th term in the sequence?
-1,-3,-9

Answers

Answer 1

Answer: -21, what ever number you have you subtract 3 from that number. So after -9 would be -12 and so on

Answer 2

Answer:

-729

Step-by-step explanation:

Given is a geometric sequence.

Therefore,

a = - 1, r = - 3 /(-1) = 3, n = 7

[tex] a_7 =? [/tex]

[tex] \because a_n = ar^{n-1} [/tex]

[tex] \therefore a_7 = (-1)(3)^{7-1} [/tex]

[tex] \therefore a_7 = (-1)(3)^{6} [/tex]

[tex] \therefore a_7 = (-1)(729) [/tex]

[tex] \therefore a_7 = -729 [/tex]

Direct answer :[tex]\color{plum}\boxed{\bold{\tt Statements :} } [/tex]segment AE and BD bisect each other. ∠BCA and ∠DCE are equal. Segment AC and segment CE are equal. Segment BC and segment CD are equal. △ACB≅△ECD

[tex]\color{plum}\boxed{\tt Reasons : }[/tex]Given. They are vertically opposite angles, so they are equal.The bisector BD divides segment AE into two equal parts which are Segment AC and segment CE.The bisector AE divides the segment BD into two equal parts which are segment BC and segment CD.△ACB≅△ECD under the SAS congruence criterion because two sides and one included angle is equal.

Steps to derive these statements and reasons :

Given :

segment AE and segment BD bisect each other

Which means :

∠BCA and ∠DCE are equal because they are vertically opposite angles. Segment AC = segment CE because the bisector BD divides the segment AE into two equal parts which are segment AC and segment CE.segment BC and segment CD will be equal because bisector AE divides the segment BD into two equal parts which are segment BC and segment CD.

Since two sides and one included angle is equal △ACB≅△ECD under the SAS congruence criterion .

1.) Maria thinks (a + b)² = a² + b². Is she correct? Justify your reasoning. ​

Answers

Answer:

No, Maria is incorrect.

(a+b)^2 is actually equal to a^2 + 2ab + b^2.

Let me know if this helps!

We now have two formulas for (a+b)², which means we can set equation 1, from earlier, and equation 2 equal to one another.

Lastly, subtract 2ab from both sides, and look there’s the Pythagorean theorem!

Question 1) Use the linear combination method to solve the system of equations. Explain each step of your solution. 2x - 3y = 13, x + 2y = -4. ( I'll post a picture of the question and problem incase there's any confusion). Will Mark Brainliest.​

Answers

Answer:

x = 2 and y = -3

Step-by-step explanation:

The given equations are:

2x - 3y = 13 ...(1)

x + 2y = -4 ...(2)

Multiply equation (2) by 2.

2x + 4y = -8 ...(3)

Subtract equation (3) from (1).

2x - 3y-(2x + 4y) = 13-(-8)

2x-3y-2x-4y = 13+8

-7y = 21

y = -3

Put the value of y in equation (2).

x + 2(-3) = -4

x-6=-4

x = 6-4

x = 2

So, the solution of the given equations are x = 2 and y = -3.

Given a point translated from A(1,2) to B(4,4). If a point C at (0,0) is translated in the same way, what will be its new endpoints?


A.(−3,−2)

B.(3,2)

C.(2,2)

D.(3,3)​

Answers

Answer:

B.(3,2)

Step-by-step explanation:

Point translated from A(1,2) to B(4,4).

This means that for x, we add 3 units(4 - 1 = 3), while for y, we add two units(4 - 2 = 2).

If a point C at (0,0) is translated in the same way, what will be its new endpoints?

0 + 3 = 3

0 + 2 = 2

So

B.(3,2)
