  • Left to Right<u> </u>

Step-by-step explanation:

<u>Step 1: Define</u>

<em>Identify</em>

a⁴ - 6b + 3b ÷ ac

<em>a</em> = -2

<em>b</em> = 6

<em>c</em> = 3

<u>Step 2: Evaluate</u>

  1. Substitute in variables:                                                                                     (-2)⁴ - 6(6) + 3(6) ÷ (-2)(3)
  2. Exponents:                                                                                                        16 - 6(6) + 3(6) ÷ (-2)(3)
  3. Multiply:                                                                                                             16 - 36 + 18 ÷ (-2)(3)
  4. Divide:                                                                                                               16 - 36 - 9(3)
  5. Multiply:                                                                                                             16 - 36 - 27

The image of the point (-1, 7) under a translation is (0, 11). Find the coordinates of the image of the point (1, -4) under the
g100num [7]

If the image of the point (-1,7) under a translation be (0,11) then the coordinates of the image of the point (1,-4) under the same translation is (2,0).

Given that the image of the point (-1, 7) under a translation is (0, 11).

We are required to find the coordinates of the image of the point (1, -4) under the same translation.​

Translation basically means the displacement of a figure or a shape from one place to another. In translation figure can move upward, downward, right, left or anywhere in the coordinate system.

The point (-1,7) after translation changes into (0,11).

X coordinate will change by adding 1 to it and Y coordinate will change by adding 4. Now the point (1,-4) will change to (2,0) after adding 1 to 1 and 4 to -4.

Hence if the image of the point (-1,7) under a translation be (0,11) then the coordinates of the image of the point (1,-4) under the same translation is (2,0).
