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:

C) y =  4 - x

Step-by-step explanation:

Boat speed = 6m/h

River speed = 2m/h

Speed of the boat in upstream = 6m - 2m = 4miles per hour.

Rate of speed decrease = 1m/h

Here x represents the number of hours.

So the speed of the boat (y) = 4 - 1x

y = 4-x

Hope this will helpful.

Thank you.

At what point does the line given by the following equation cross the y-axis? y = (6/9)X + 9
Elodia [21]

Answer:

D

Step-by-step explanation:

the equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

y = \frac{6}{9} x + 9 ← is in slope- intercept form

with y- intercept c = 9

then the line crosses the y- axis at (0, 9 )
