Question

David is rowing a boat upstream. The river is flowing at a speed of 2 miles per hour. David starts rowing at a speed of 6 miles per hour, but as he gets tired his speed decreases (at a rate of 1 mile per hour, every hour). Which equation represents the speed of the boat for x hours spent rowing?
y = x + 4
y = x − 4
y = 4 − x
y = 6 − x
y = 6 − 2x

Answer 1

y = 4 - x is your answer here

Answer 2

thank you
/.\

Answer 3

Given equations A and B as and , respectively, which expression will eliminate the variable x?
A + B
A − B
A + B
A − B
A + B

Answer 4

can u help on that ?

Answer 5

he starts at 6 mph and the river is against him at 2 mph so 4 and then its - 1 per hour so make that x so ya y=4-x

Answer 6

are there equations there in the blank spaces or no?

Answer 7

no /.\ it didnt copy right one second

Answer 8

Given equations A and B as 2/5x+y=12 and 5/2y-x=6 , respectively, which expression will eliminate the variable x?

Answer 9

@dan815 did this one so im going to go with what he put. 5/2 A - B is your answer
