Step-by-step explanation:
Step one:
Speed uphill 100meters per hour
Speed on flat ground 120 meters per hour
Speed uphill 150 meters per hour.
Required
The average speed.
Step two:
To get the average speed, let us add all the individual speeds and divide by 3(three different speeds), then multiply the result by 2(the return trip)
Average speed= (100+120+150)*2/3
Average speed= 740/3
Average speed= 246.6 meters per hour
Answer:
(-5 1/9, -4)
Step-by-step explanation:
Add the equations
5y=-20
y=-4
-9x+8(-4)=22
-9x-32=22
-9x=46
x= - 5 1/9
A positive correlation means sales are rising because of advertising
the steeper the chart the more money is being made, so the owner would be happier with a steeper slope
