Answer:

Step-by-step explanation:

I mean average rate of change literally means rise / run or slope

So you rise 0 and run 2

-- = 0 = rate of change (wow that's a nice rate of change lol XD)

Answer:

This is a linear graph.

Step-by-step explanation:

Since the x values increase at a constant of 1. The y-values have a 1st difference of -4 which means the graph is linear.

x and 4x are supplementary to each other, meaning they add up to 180. So your equation is 180=5x. Divide both sides by 5 to get 36=x.

A company manufactures and sells video games. A survey of video game stores indicated that at a price of $66 each, the demand wo

Answer:

$y=-30x+2380$

Step-by-step explanation:

$x\rightarrow$ represent price per video game.

$y\rightarrow$ represent demand.

The linear equation in slope intercept form can be represented as:

$y=mx+b$

where $m$ is slope of line or rate of change of demand of game per dollar change in price and $b$ is the y-intercept or initial price of game.

We can construct two points using the data given.

When price was $66 each demand was 400. $(66,400)$

When price was $36 each demand was 1300. $(36,1300)$

Using the points we can find slope $m$ of line.

$m=\frac{y_2-y_1}{x_2-x_1}$

$m=\frac{1300-400}{36-66)}$

$m=\frac{900}{-30}$

$m=-30$

Using point slope form of linear equation to write the equation using a given point.

$y-y_1=m(x-x_1)$

Using point $(66,400)$ .

$y-400=-30(x-66)$

⇒ $y-400=-30x+1980$ [Using distribution]

Adding 400 to both sides:

⇒ $y-400+400=-30x+1980+400$

⇒ $y=-30x+2380$

The linear relationship between price and demand can be written as:

$y=-30x+2380$

6 8/9 times 36/31 .....

aivan3 [116]

Answer:

Step-by-step explanation:

First, convert the mixed fraction to an improper one:

$\displaystyle{6\frac{8}{9}=\frac{62}{9}}$

Then, multiply:

$\displaystyle{\frac{62}{9}\times\frac{36}{31}}$

Cross-reduce:

$\displaystyle{\frac{2}{1}\times\frac{4}{1}}$

And simplify:

$\displaystyle{\frac{8}{1}=8}$
