Global mean temperature was changing the most rapidly in 2005. How quickly was the temperature changing in 2005

AysviL [449]

The temperature was changing at a rate of 2.925 degrees Celsius in 2005

<h3>How to determine the rate in 2005</h3>

From the graph (see attachment), we have the following ordered pair

(x,y) = (5,14.625)

The above means that, the temperature in 2005 is 14.625 degrees Celsius

So, the rate in 2005 is:

$Rate = \frac{14.625}{5}$

$Rate = 2.925$

Hence, the temperature was changing at a rate of 2.925 degrees Celsius in 2005

A company sells two versions of an antivirus software. The home edition costs $23.50, and the business edition costs $58.75. Las

Kamila [148]

Answer:

x + y = 745

23.50x + 58.75y = 29,668.75

Step-by-step explanation:

Since 745 copies were sold and x represents the number of copies of the home edition sold and y represents the number of copies of the business edition sold:

x + y = 745

Since the home edition costs $23.50, and the business edition costs $58.75:

The money earned from home edition is = 23.50x

The money earned from business edition is = 58.75y

Since the company earned $29,668.75:

23.50x + 58.75y = 29,668.75
