Choose two statements (the original conditional statement and its converse) that could form the biconditional "x = 1 if and only if x - 1 = 0."
0 A. If x-1 = 0, then x = 1.
B. If x= 1, then x-10.
C. If x = 1, then x-1 = 0.
m D. If x = 1, then x-1 +0.

the function makes a strait line horizontally with no x intercept but a y intercept at 9.

(23*2)-12=x     x=34

step-by-step explanation:

answer: median

step-by-step explanation:

the median is the middle value when a data set is ordered from least to greatest

- "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."
