Slope is equal to the change in

over the change in

, or rise over run.

m = change in y / change in x

The change in

is equal to the difference in x-coordinates (also called run), and the change in

is equal to the difference in y-coordinates (also called rise).

m = y^2 - y^1 / x^2 x^1

Substitute in the values of

and

into the equation to find the slope.

Answer:

Step-by-step explanation:

Δy = -6 - 3 = -9

Δx = -15 - 8 = -23

slope = Δy/Δx = 9/23

The following graph shows the consumer price index (CPI) for a fictional country from 1990 to 2000.For which of these time perio

KatRina [158]

Answer:

Option B. 1990 - 1992

Step-by-step explanation:

If we have to calculate inflation rate in year 2000 from 1990, we use the formula

$inflation=\frac{C.P.I. 2000-C.P.I. 1990}{C.P.I 1990}\times 100$

which means if consumer price index is increasing year by year the inflation rate will increase.

Now we analyse our options given with the help of graph given.

A. from 1994 - 2000

Consumer price index increased from year 1994 to 1998 but decreased between 1998 to 2000.

So this option doesn't show the continuous inflation.

B. Year 1990 - 1992

We find a continuous increase in C.P.I. therefore there will be a continuous increase in inflation.

So this option is correct.

C. Year 1992 - 1996

In this gap we see deflation from year 1992 to 1994 then inflation between 1994 - 1996.

So there is ups and downs in this period showing discontinuity in inflation.

D. 1992 - 1994

There is continuous decrease in C.P.I. so continuous deflation is reported between this period.

It's not the correct option.

Answer is Option B.

A coffee shop uses two different-sized bins to store coffee beans. The volume of the smaller bin is x cubic inches and the volum

raketka [301]

Answer:

Total volume of all the bins = xS + yL

Step-by-step explanation:

Given: x cubic inches represent the volume of the smaller bin and y cubic inches represents the volume of the larger bin. The store has S smaller bins and L larger bins.

To find: an expression that represents the total volume of all the bins

Solution:

The volume of the smaller bin = x cubic inches

The volume of the larger bin = y cubic inches

Also, the store has S smaller bins and L larger bins

So,

Total volume of all the bins = xS + yL
