Answer: a) 70 mph
b) 80 mph
Step-by-step explanation:
Given that Kayleen left home at noon and drove to boston.she got there at 4:00. Then time spent will be 4 hours . Noon means 12pm
Distance covered = 280 miles kayleens average speed will be
Speed = distance/time
Speed = 280/4 = 70 mph
Given that Elijah was already 40 miles closer than Kayleen was when she started
Distance covered by Elijah will be
Distance = 40 + 280 = 320
Time = 4 hours
Speed = 320/4 = 80 mph
Answer:
steps below
Step-by-step explanation:
This is a contradictory proof of sophistry
f(x+4) = f(x)+f(4) ...(1) when x=0
f(x+4) = f(0+4) = f(4) = f(x) + f(4)
f(x) = f(4)-f(4) = 0
From (1): f(x) = f(x+4) - f(4)
x=-4 <u> f(-4)</u> = f(-4+4) - f(4) = f(0) - f(4) = <u>-f(4)</u> ...(2)
From (1): f(x+4) = f(x)+f(4)
x=4 f(4+4) = <u>f(8)</u> = f(4) + f(4) = 2f(4) = <u>-2f(-4)</u> from (2) ... (3)
f(8) +2f(-4) = -2f(-4) + 2f(-4) = 0
-6 = y/5 + 4
Step 1: Subtract 4 from each side of the equation.
Step 2: Multiply each side by 5.
If you don't arrive at the solution y= -50 , then return to Step-1
and repeat the process, being on the lookout for your mistake.
