There are a total of 64 students in a drama club and a yearbook club. the drama club has 10 more students than the yearbook club.
a. write a system of linear equations that represents this situation. let x
represent the number of students in the drama club and y
represent the number of students in the yearbook club.
system of equations: x=?
? x+? y=64

- "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."

a - base

b - exponent

so,
