Answer:

Step-by-step explanation:

an = a1 * (-2)^(n - 1)

a1 = 4

a2 = 4 * (-2)^1

a2 = 4 * -2

a2 = - 8

a3 = 4 * (-2)^(n - 1)

a3 = 4 * (-2)^2

a3 = 4 * 4

a3 = 16

an = 4 * (-2)^(n - 1)

an = 4 * (-2)^-1 * (-2)^n

an = 4/(-2) (-2)^n

an = -2 * (-2)^n

Now this is how you know. You know that a4 = - 32. So try your modified formula

a4 = - 2 * (-2)^4

a4 = -2 * 16

a4 = - 32

Is the system of equations consistent, consistent and coincident, or inconsistent? y=3x+4y=3x+3 Select the correct answer from t
Genrish500 [490]

Answer: Inconsistent

<u>Step-by-step explanation:</u>

y = 3x + 4   → m = 3, b = 4

y = 3x + 3   → m = 3, b = 3

These equations have the same slope but different y-intercepts so they are parallel lines <em>which means they will never intersect.</em>

NOTES

  • one solution: consistent & independent        <em>lines cross</em>
  • infinite solutions: consistent & dependent     <em>same line</em>
  • no solution: inconsistent                                  <em>parallel lines</em>
