in her kayak bunny can travel 70 miles downstream with the current in 5 hours. the return trip against the current takes 7 hours

Alinara [238K]

9514 1404 393

Answer:

kayak: 12 mph
current: 2 mph

Step-by-step explanation:

Bunny's rate downstream is ...

(70 mi)/(5 h) = 14 mi/h = k + c

Bunny's rate upstream is ...

(70 mi)/(7 h) = 10 mi/h = k -c

The kayak speed is the average of these:

(14 mi/h +10 mi/h)/2 = ((k +c) +(k -c))/2

(24 mi/h)/2 = 2k/2

12 mi/h = k

Then the current speed is ...

c = k -10 = 12 -10 = 2 . . . . mi/h

The still-water speed of the kayak is 12 mi/h; the speed of the current is 2 mi/h.

_____

Additional comment

World-class kayak paddlers will not maintain a speed more than 8 mi/h for that distance and/or time (140 miles in 12 hours). Bunny is exceptional.

Find x (2x+1) (5x+5)

mezya [45]

explanation;

Solution for 2x+1=5x-5 equation

Simplifying

2x + 1 = 5x + -5

Reorder the terms:

1 + 2x = 5x + -5

Reorder the terms:

1 + 2x = -5 + 5x

Solving

1 + 2x = -5 + 5x

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-5x' to each side of the equation.

1 + 2x + -5x = -5 + 5x + -5x

Combine like terms: 2x + -5x = -3x

1 + -3x = -5 + 5x + -5x

Combine like terms: 5x + -5x = 0

1 + -3x = -5 + 0

1 + -3x = -5

Add '-1' to each side of the equation.

1 + -1 + -3x = -5 + -1

Combine like terms: 1 + -1 = 0

0 + -3x = -5 + -1

-3x = -5 + -1

Combine like terms: -5 + -1 = -6

-3x = -6

Divide each side by '-3'.

x = 2

Simplifying

x = 2

Answer:

$\boxed{D. 3 {x}^{2} - x - 6}$

Given:

$f(x) = 3{x}^{2} - 4 \\ \\ g(x) = x + 2$

To Find:

$(f - g)(x) = f(x) - g(x)$

Step-by-step explanation:

$= > f(x) - g(x) = (3{x}^{2} - 4) - (x + 2) \\ \\ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: = 3{x}^{2} - 4 -(x) - (2)\\ \\ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: =3{x}^{2} - 4 - x - 2\\ \\ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: =3 {x}^{2} - x - 6$
