Which of the following descriptions represent the transformation shown in the image? Part 3b<br>​
Igoryamba

Answer:  d) none of the above

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

Start at Black Triangle: B = (0, -4)   C = (4, -1)   D = (2, -5)

End up at Red Triangle: B = (2, 0)  C = (-2, 3)   D = (0, -1)

Rotation of 180°: (x, y) → (-x, -y)

Reflection across y-axis: (x, y) → ( -x, y)

Reflection across x-axis: (x, y) → (x, -y)

Reflection across x=1: (x, y) → (2 - x, y)

a) \\\begin{array}{ccc}\qquad \text{(x, y)}&\text{Rotate 180}^o&\text{reflect across y-axis}\\B:\ (0, -4)&(0, 4)&(0,4)\\C: (4, -1)&(-4,1)&(4,1)\\D: (2, -5)&(-2,5)&(2,5)\end{array}

b) \\\begin{array}{ccc}\qquad \text{(x, y)}&\text{Rotate 180}^o&\text{reflect across x = 1}\\B:\ (0, -4)&(0, 4)&(2,4)\\C: (4, -1)&(-4,1)&(6,1)\\D: (2, -5)&(-2,5)&(4,5)\end{array}

c) \\\begin{array}{ccc}\qquad \text{(x, y)}&\text{Rotate 180}^o&\text{reflect across x-axis}\\B:\ (0, -4)&(0, 4)&(0,-4)\\C: (4, -1)&(-4,1)&(-4,-1)\\D: (2, -5)&(-2,5)&(-2,-5)\end{array}

None of the given options transform the black triangle onto the red triangle.

Evaluate the expression for x = 2. -9x2 + 11x − 7 =
harina [27]

All you have to do is replace every x with 2 and then solve:

<em>Make to sure to follow the Order of Operations!!</em>

-9x(2) + 11x - 7 =

(-9 × 2 × 2) + (11 × 2) - 7 =

-36 + 22 - 7 =

-14 - 7 =

-21

The answer is -21.

Hope that helps!
