Which shows the pre-image of triangle X'Y'Z' before the figure was rotated 90° about the origin?

Oksanka [162]

Answer:

pre-image XYZ is X (2, 2), Y (6, 0), Z (1, -1)

The above is the second option in your question.

Step-by-step explanation:

a triangle has points X' (-2, 2), Y' (0, 6), Z' (1, 1)

To rotate the above triangle -90° about the origin you invert the x & y values and change the sign on the new y value.

pre-image XYZ is X (2, 2), Y (6, 0), Z (1, -1)

Solving for H:

h = 3 v/lw = 3 x 42/ 36 x 24

Help please. Screenshot included.

The following information will help us with this problem:

$\sqrt[m]{x^n} = x^{\frac{n}{m}$

When we use that information in the context of this problem, we can find:

$\sqrt[4]{15^7} = 15^{\frac{7}{4}}$

Thus, a = 15, b = 7, and c = 4.
