Answer:

a1 = -1/8

Step-by-step explanation:

-4 × 1/2 = -2

-2 × 1/2 = -1

-1 × 1/2 = -1/2

-1/2 × 1/2 = -1/4

-1/4 × 1/2 = -1/8

If n + 7 = 10, evaluate 2n - 2<br> O 3<br> 0 17<br> 4<br> 6
Alexandra [31]

Answer:

The value of 2n - 2 is 4.

Step-by-step explanation:

Given the equation

n + 7 = 10

Subtract  7 from both sides of the equation

n+7-7=10-7

Simplify

n=3

Now substituting n = 3 in the equation

2n - 2 = 2(3) - 2

          = 6 - 2

          = 4

Therefore, the value of 2n - 2 is 4.

It is helpful to plot the points, then mentally test the answers for plausibility. Translation of E 1 unit to the right puts it at (2, 1), then rotation counterclockwise 90° about the origin puts it at (-1, 2), the location of E'.

The appropriate choice seems to be
  A translation 1 unit to the right followed by a 90-degree counterclockwise rotation about the origin


_____
Translation 1 unit right: (x, y) ⇒ (x+1, y)
Rotation 90° CCW: (x, y) ⇒ (-y, x)
Both transformations in that order: (x, y) ⇒ (-y, x+1)
