Jack's goal is to lose 4.25 pounds every month. If he keeps this up, how much weight will he have lost after 9.5 months? round to the nearest hundredth

40.38 pounds (rounded)

Step-by-step explanation:

4.25 times 9.5

40 pounds

Step-by-step explanation:

4.35x9.5=40.375

if you round the answer/40.375

You get 40

Therefore, the answer is 40 pounds

answer: -2+√x,-2-√x

i hope this , i don't know if you're looking for a pair or not.

- "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."
