-14x-14 = 196 then subtract -6 from 196 because they'll cancel each other out. the answer is 190.
(1,-1)
(-4,2)
(-2,1)
I believe these will work
<span>Let time taken by Luke to cover the distance = x hours
Speed of Luke = 6 miles per hour
Therefore, Distance covered by Luke = 6x ------(1)
Speed of Micah = 4 miles per hour
Since Micah walked 2 miles before Luke started running, Luke started 1/2 an hour after Micah started.
Therefore time taken by Micah to cover the distance = x+1/2
Distance covered by Micah = 4(x + 1/2) -------(2)
Equating (1) and (2)
6x = 4(x+1/2)
6x = 4x +2
2x = 2
x= 1
Therefore Luke would take 1 hour to cover the distance covered by Micah.</span>
Step-by-step explanation:
Look at the picture below
I am assuming you meant to write f(x) = 3^x -2
f(3) = 3^3 - 2 <=>
f(3) = 27 - 2 <=>
f(3) = 25
