The price of compact fluorescent light bulbs fell because of improvements in production technology. As a result, the demand for
Dmitry_Shevchenko [17]

Answer:

This statement if FALSE

Step-by-step explanation:

This question deals with the concept of competing products and how the price of a product effects its demand

There are two competing bulbs

a) Compact fluorescent light bulbs

b) Incandescent light bulbs

The first statement exclaims that the price of the product (a) decreases and this causes the demand of product (a) to increase, this would decrease the demand of product (b) as they are competitors.

To retaliate against the loss of sales of product (b) the price of product (b) is decreased, this should increase the demand of product (b) but the statement says the the demand of product (b) further decreases.

Since we know from the statement that sales were primarily driven by the price of the products, the demand of product (b) should have increased. Hence this statement is false

Graphing inequality's
Pani-rosa [81]

Answer :

\boxed{\textsf {The red area is the required answer . }}

Step-by-step explanation:

A linear inequality in two variables is given to us and we need to plot it's graph .So the the given inequality is ,

\sf\implies y \geq- \dfrac{1}{5}x +5

So firstly let's simplify out the inequality for easy plotting of the graph .

\sf\implies y \geq- \dfrac{1}{5}x +5 \\\\\sf\implies y \geq \dfrac{-x+5(-5)}{5}\\\\\sf\implies y \geq \dfrac{-x-25}{5}\\\\\sf\implies y \geq -(1)\dfrac{x+25}{5}

Now let's put some values of x to get values of y .

• Firstly put x = 0 then we get , y is greater than or equal to 0+5/5 (-1) = 5/5(-1) = -1 . Hence we get y ≥ (-1) .

• Secondly put x = 1 , then we get , y is greater than or equal to 1+5/5(-1)=6/5(-1) = -6/5 . Hence we get y ≥ -6/5 .

• Thirdly put x = -1 , then we get y is greater than or equal to -1+5/5(-1) = -4/5 . Hence we get y ≥ -4/5

• Fourthly put x = (-5) , then we get y is greater than or equal to -5+5/5(-1) = 0 .Hence we get y ≥ 0 .

With reference to these let's plot a graph . For the graph kindly refer to the attachment :) .

Here in the graph the red area shows the possible values of x and y .

I have to write the equation of the line in slope intercept from that crosses through the ordered pairs (2,-2) and (4,1)
jekas [21]
First find slope=m=(y2-y1)/(x2-x1). In this case:

(-2-1)/(2-4)=m=-3/-2

m=1.5, and since we are making a line of the form y=mx+b we have so far:

y=1.5x+b, now using either point, (2,-2) we can solve for b, the y-intercept:

-2=1.5(2)+b

-2=3+b

b=-5

So our line is:

y=1.5x-5
