Answer:

equation is y=1.3x-12.4

Step-by-step explanation:

Step one

Given that the points are

(0,7) (8,-2)

X1=0

X2=8

Y1=7

Y2=-2

Step two :

Let us find the Slope

Pluging our points we have

M= (Y2-Y1)/(X2-X1)

M=(-2-7)/(8-1)

M=-9/7

M=1.3

Step three :

We know that the equation of a line is given by

Y=Mx+c

Hence the intercept is

-2=1.3*8+c

-2=10.4+c

-12.4=c

c=-12. 4

Hence the equation is y=1.3x-12.4

The vertex of the graph of f(x)=|X-3|+6 is located at
frosja888 [35]

The vertex of the graph of f(x)= |x-3|+6 is located at (3, 6)

<h3>How to determine the vertex?</h3>

The equation of the function is given as:

f(x) = |x - 3| + 6

The above function is an absolute value function.

An absolute value function is represented as:

f(x) = a|x - h| + k

Where:

Vertex = (h, k)

By comparison, we have:

Vertex = (3, 6)

Hence, the vertex of the graph of f(x)= |x-3|+6 is located at (3, 6)

Suppose that the revenue function for a certain product is given by R(x) = 17(2x + 1)−1 + 34x − 17 where x is in thousands of un
REY [17]

Answer:

Step-by-step explanation:

Given that:

R(x) = \frac{17}{2x+1} + 34x − 17

As we know that derivative of revenue function is marginal revenue function .

We will use following rules of derivative

=> dR/ dx = \frac{-17*2}{(2x+1)^{2} } + 34

=> R' (x) =   \frac{-34}{(2x+1)^{2} } + 34

=> R '(2000) =  \frac{-34}{(2*2000+1)^{2} } + 34 = 34

The revenue when 2000 units are sold is:

R(2000) = \frac{17}{2*2000+1} + 34*2000 − 17 = $69,783
