The variable x represents (d) The width of the deck

<h3>How to determine what x represents?</h3>

The statement is given as:

<em>length of a deck is twice its width</em>

<em />

This means that:

Length = 2 * Width

The equation is given as:

y = 2x

By comparing both equations, we have:

Length = y

Width = x

This means that x represents (d) The width of the deck

Find the slope and the equation of the line tangent to f (x )equals StartFraction 2 x minus 1 Over x plus 7 EndFraction at x =

kondor19780726 [428]

Answer:

$y=\frac{5}{27} x-\frac{1}{27}$

Step-by-step explanation:

$f(x)=\frac{2x-1}{x+7}$

To find slope of f(x) at x=2, find the derivative f'(x)

apply quotient rule to find derivative

$f(x)=\frac{2x-1}{x+7}\\f'(x)=\frac{2(x+7)-1(2x-1)}{(x+7)^2} \\f'(x)=\frac{15}{(x+7)^2}$

f'(x) is the slope . Now find slope at x=2. plug in 2 for x

$f'(x)=\frac{15}{(x+7)^2}\\f'(2)=\frac{15}{(2+7)^2}=\frac{5}{27}$

find out f(x) when x=2

$f(x)=\frac{2x-1}{x+7}\\f(2)=\frac{2(2)-1}{2+7}=\frac{1}{3}$

Now frame the equation of the line

(2,1/3) slope = 5/27

$y-y_1=m(x-x_1)\\y-\frac{1}{3}=\frac{5}{27} (x-2)\\y-\frac{1}{3}=\frac{5}{27} x-\frac{10}{27}\\\\y=\frac{5}{27} x-\frac{1}{27}\\\\$

When 14 is subtracted from 6 times a number, 40 is

Rzqust [24]

Answer:

4.5

Step-by-step explanation:

Let the number be x

6x-14 = 40

Add 14

6x = 40+14

6x = 54

Divide by 6

6x/6 = 54/6

x = 9

We want 1/2 of the number

1/2 of 9 is 4.5
