Enter the ordered pair for the vertices for r(90°, o)(QRST).​

Given:

The vertices of a polygon QRST are T(-2, 3), Q(1, 5), R(3, -1) and S(0, 0).

To find:

The vertices for .

Solution:

The rule  represents refection of polygon QRST across the x-axis.

If a figure is reflected across the x-axis, then

Using this rule, we get

Therefore, the vertices for  are T'(-2, -3), Q'(1, -5), R'(3, 1) and S'(0, 0).

Step-by-step explanation:

-13

step-by-step explanation:

f(x)=2x-5 for f(-4)

f(-4)   means let x=-4

f(-4) = 2(-4) -5

f(-4) =-8-5

      = -13
