Arrange the systems of equations that have a single solution in increasing order of the x-values in their solutions. 2x + y = 10
x − 3y = -2

x + 2y = 5
2x + y = 4

x + 3y = 5
6x − y = 11

2x + y = 10
-6x − 3y = -2

- "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."

what are the statements? and what do you mean by "216 2 1 6"?

cpctc makes it so that corresponding parts of the triangle you proved to be equal are equal, the other options aren't part of the part of the triangles you proved to be equal.
