HELP ME, ASAP I DONT GET THIS. PLS PLS PLS Angle PQR is formed by segments PQ and QR on the following coordinate grid: A coordinate grid is shown from positive 6 to negative 6 on the x-axis and from positive 6 to negative 6 on the y-axis. A line segment PQ is shown with P as ordered pair negative 1, negative 1 and Q as ordered pair negative 5, negative 4. Another line segment QR is shown with R as ordered pair negative 1, negative 4. Angle PQR is rotated 90 degrees counterclockwise about the origin to form angle P'Q'R'. Which statement shows the measure of angle P'Q'R'?

A. m∠P'Q'R' = 90 degrees
B. m∠P'Q'R' = 180 degrees
C. m∠P'Q'R' = m∠PQR
D. m∠P'Q'R' = 2 ⋅ m∠PQR

- "runner b is moving at a slower rate."

- "the graphs shown are graphs of distance(km) against time(min).

the slopes of this graphs are are given by:

slope = (change in y)/(change in x)

= (change in distance)/(change in time)

this is the formula for finding the speed. so, the slope of these graphs represent the speed of the runner.

taking each division in the graph to represent 1 on both axis:

runner a ⇒ speed = (2-0)/(1-0)

= 2/1

= 2 km/min

runner b ⇒ speed = (3-0)/(3-0)

= 3/3

= 1 km/min

this shows that   runner b is moving at a slower rate."

nope lol

step-by-step explanation:

use distributive property on all like terms and change your signs if you have a double negative or if you have positive/negative

-1/4 > -1 2/3. -1/4 is greater than -1 2/3 because it is closer to 0 on the number line.
