Answer:
<em>Reflecting over the x-axis and then reflecting over the line y = x. </em>
Step-by-step explanation:
<em>A rotation 90° counterclockwise will map every point (x, y) to (-y, x).</em>
<em></em>
<em>Since the x- and y-coordinates are switched, this is not a reflection across the x-axis followed by a reflection across the y-axis.</em>
<em></em>
<em>Since the y-coordinate is negated and the x- and y-coordinates are switched, this is not a translation.</em>
<em></em>
<em>Reflecting across the x-axis will negate the y-coordinate, giving us (x, -y). Following this with a reflection across y=x will switch the coordinates giving us (-y, x). This is the correct transformation.</em>
Answer:
$35
Step-by-step explanation:
divide 25 by 5 to get the unit rate and then take that and multiply that by 7
Answer:
7740 degrees.
Step-by-step explanation:
The sum of the exterior angles of all polygons add up to 360 degrees.
So the number of sides and the number of interior angles in this polygon = 360 / 8 = 45.
Each internal angle = 180 - 8 = 172 degrees, so the sum of all interior angles
= 172 * 45
= 7740 degrees,
