10. A parabola has an axis of symmetry x = 2 and one of the x-intercepts is x =5. Where is the other x-intercept?

-1

Step-by-step explanation:

5-2=3

2-3=-1

step-by-step explanation:

how many centimeters did the level of the salsa go down by?

- "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."
