Step-by-step explanation:
Distance from,
There = 50
and Back = 50
speed is...
There = 25+5
Back = 25-5
50/25+5 = 50/30 = 5/3
50/25-5 = 50/20 = 5/2
5/3+5/2 = Total Time spent to go from pier a to pier b and back
Total Time = 25/6 Hours
Answer:
x=2
Step-by-step explanation:
on the LHS multiply the 6 by the values in the brackets and add by 2x= 9-(x+6) RHS
for the RHS multiply the - by (x+6) which will be 9-x-6
therefore you'll put in your like terms towards the end it'll be 6x-12=0 then take it to the other side and divide by 6 which will give you 2
The critical point is (-30,0) I think
