The first term is 7. The common ratio is -7/7 = -1. The general formula for the nth term of a geometric sequence can be used:
  an = a1·r^(n-1)
  an = 7·(-1)^(n-1)

Kinesthetic leaner best learn in formation
valina [46]
Metacognition's best definition can be described as an awareness and understanding of one's own thought processes. Answer A is obviously the incorrect choice as it refers to English, not psychology. Answer choice B makes sense as those who understand their own thought processes may be good test takers. Answer choice C is about learning new things which I would say does not necessarily apply to understanding what you know. It is about new knowledge whereas metacognition is about old knowledge. The final answer choice, D, does not apply since metacognition is not a process, but an awareness. I would say that the most applicable answer choice is B.

Hope that helps!

Nutka1998 [239]

Answer:

X=-1

Y=1

Step-by-step explanation:

6x-12y

-18

) 6x + 4y

-

-2

Subtract the two equations

6x - 12y - (6x + 4y) = -18 - (-2)

Determine the sign

6x- 12y - 6x- 4y

=-18 + 2

Simplify

-12y

- Ay

=-18 + 2

Solve the equation

Substitute

6×+4

-2

Solve the equation

Choose the system of equations which matches the following graph:
Kipish [7]

3x - 2y = 8

- 2y = 8 - 3x

2y = 3x - 8

y = 1.5x - 4

This is the red graph

6x - 4y = 20

- 4y = 20 - 6x

4y = 6x - 20

y = 1.5x - 5

This is the blue one.

So it must be answer d)

Which scales are equivalent to 1 inch to 1 foot? Select all that apply. Group of answer choices 1 to 12 (1/12) to 1 100 to 0.12
Bad White [126]

Answer:

  • 1 to 12
  • 5 to 60
  • 9 to 108

Step-by-step explanation:

There are 12 inches in one foot so the equivalent ones are:

1 to 12

This shows that there are 12 inches in one foot so is equivalent.

5 to 60

5/60 = 1/12

This is equivalent because it shows that 12 inches are required to make a foot.

9 to 108

9/108 = 1/12

This is also equivalent for the same reasons as above.
