Answer:

Step-by-step explanation:

Start by multiplying everything by 320, so that the y gets a unit factor:

$\frac{320}{16}x + \frac{320}{320}y - 29\cdot320 = 0$

simplify

$20x + y - 9280 = 0$

Now isolate y on the left:

$y = 9280 - 20x$

Change the equation y= in to a function of x:

$f(x) = 9280 - 20x$

24 = 6 * 4
and
6 + 4 = 10

so its the last choice.

Let f(x) = 1/x . Find the number b such that the average rate of change of f on the interval [2, b] is − 1/8

vekshin1

Answer:

b=4

Step-by-step explanation:

So, we have the function $f(x)=1/x$ . We need to find b such that the average rate of change or the slope is -1/8 between the intervel [2, b]. First, let's find f(2).

f(2) = 1/(2) = 1/2

So, we have the point (2, 1/2)

At point b, f(b) = 1/b.

Let's plug this into the slope formula:

$\frac{y_2-y_1}{x_2-x_1}=\frac{.5-\frac{1}{b} }{2-b} =-1/8$

Now, we just need to solve for b. First, let's multiply both the numerator and denominator by b (to get rid of the annoying fraction in the numerator).

$\frac{.5b-1}{2b-b^2} =\frac{-1}{8}$

Now, cross multiply.

$4b-8=b^2-2b$

$b^2-6b+8=0$

Solve for b. Factor using the numbers -4 and -2.

$=(b-4)(b-2)=0$

Thus, b=4 or b=2.

However, b=2 is not a possible solution since the interval [2,2] means nothing. Thus, b=4.

Answer:

The solution h < 5.5 means that Melanie can rent the bike for no more than 5.5 hours.

<u>Hope this helps :)</u>

<u>Explanation and Check part below.</u>

Step-by-step explanation:

1. Isolate the variable by doing the inverse operation which is in this case subtracting 6 on bothsides of the equation.

8h + 6 < 50

- 6 - 6

8h < 44

2. Dive both sides of the equation by 8.

8h < 44

--- ----- <--------- fraction bar, divide

8 8

h < 5.5
