A motorboat takes 5 hours to travel 100 kilometers going upstream. The return trip takes
tatuchka [14]

Step-by-step explanation:

Let's say b is the rate of the boat in still water, and c is the rate of the current.

Distance = rate × time

Going upstream:

100 = (b − c) (5)

20 = b − c

Going downstream:

100 = (b + c) (2)

50 = b + c

Solve the system of equations using substitution or elimination.  Using elimination, add the equations together:

70 = 2b

b = 35

c = 15

The boat's speed is 35 km/h, and the current's speed is 15 km/h.

What is the equation in slope-intercept form of the line that passes through the points (4, 5) and (8,3)?
larisa86 [58]

Answer:

y = -1/2x+7

Step-by-step explanation:

First find the slope using the slope formula

m = ( y2-y1)/(x2-x1)

   = (3-5)/( 8-4)

   = -2/4

  = -1/2

The slope intercept form is

y = mx+b where m is the slope and b is the y intercept

y = -1/2x+b

Substitute a point into the equation

3 = -1/2(8) +b

3 = -4+b

Add 4 to each side

3+4 = -4+b+4

7 = b

y = -1/2x+7

Below are two different functions, f(x) and g(x). What can be determined about their y-intercepts?
IrinaVladis [17]
F(x) = 4x-1, so the y-intercept is 4(0)-1 = -1
g(x) = x+2, so the y-intercept is (0)+2= 2
<span>(B) The function g(x) has a higher y-intercept.
