Bill and Amy travel the same distance from home to school of 14.4 kilometers. Amy takes 40 minutes of time to arrive to school which means she has a rate of 14.4 km /40 minutes or 6 meters/ second. Bill takes a total 60 minutes to arrive to school. Hence Bill's rate is equal to 14.4 km/60 minutes or 4 meters/ second.Amy's is 2 m/s faster than Bill's speed, then.

What two numbers multiply to get neg 240 and what two same numbers add to get neg 8
ahrayia [7]
Make the number x & y
x*y=-240240
x+y=-8 < you can rearrange this as x=-8-y
Now substitute in this rearrangement
(-8-y)*y=-240
-8y-y² =-240 (add y² and 8y)
0=y²+8y-240 (now factorise the equation)
0=(y+20)(y-12) (for 2 things to multiply and equal zero one or both has to equal zero)
so y+20=0 and/or y-12=0
so y=-20 or y=12
Now substitute these into x+y=-8 to get x
y=-20 then x=12
y=12 then x=-20

As the weight of purchased items increases, the shipping charges increase, as shown in the table below. Weight, in oz Total Ship
ankoles [38]
The correct answer is beginning at 5 ounces, the graph is discontinuous every 5th integer of the domain.

It is a step function; there is not a continuous increase between values.  The shipping level is fixed for each price, then jumps to the next tier.  This will be a discontinuous graph.
