Here is my question please anwser as soon as possible

is it asking which one is a y coordinate?

Q'(5, -3), R'(4, -1), S'(0, -2), T'(0, -5)

Step-by-step explanation:

Reflecting across the y-axis causes the x coordinate of a point to change to its opposite. So in terms of x and y: (x, y) ⇒ (-x, y)

Q(-5, -3) ⇒ Q'(5, -3)

R(-4, -1) ⇒ R'(4, -1)

S(0, -2) ⇒ S'(0, -2)

T(0, -5) ⇒ T'(0, -5)

- "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."

answer: 12   they all have at least 28 days
