Question

i will medal and fan for help with 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?

Answer 1

y = 6 − 2x

y = 4 − x

y = x + 4

y = 6 − x

y = x− 4

Answer 2

y=6-2x
y=4-x
y=x+4
y=6-x
y=x-4

Answer 3

is their more than 1 answer choice?

Answer 4

those 5 are the answer choices

Answer 5

but theres only 1 answer out of all of them correct?

Answer 6

yea i know i need to know which one of those 5 are my answer

Answer 7

@iGreen

Answer 8

DECREASES at a rate of 1 mile per hour

This would be subtracting 'x'.

He's rowing upstream, the speed of the river is 2MPH, and he's rowing 6 MPH.

So what's 6 - 2?

Answer 9

4

Answer 10

Yes, so we have 4 - x.

So our answer is:

y = 4 - x

Answer 11

y=x-4

Answer 12

No, that's close..we subtract 'x' though..not '4'..

Answer 13

thank you can you help me with another one

Answer 14

What is the slope and y-intercept of the equation represented by the following graph?

slope = 2, y-intercept =-1/2

slope = -2, y-intercept =-1/2

slope =-1/2, y-intercept = 2

slope =1/2 , y-intercept = 2

slope = -1, y-intercept = 2

Answer 15

Sure, just close this one and oepn a new one.
