It's about the science of predictions that says how the world will be in future . Then, there's also Statistics that also shows the way our world is evolving. Thirdly, forecasting has equal importance in doing that, like town population graphs or cow growth rate. All these use graphs and ratios in order to get a visual information about our enquiries, be it in Medicine, Biology, the Earth movement or the Universe.

Which inequality is represented by the graph
castortr0y [4]
Well, accordingly to the graph, it has a positive slope so we can eliminate b and d. So it is either a or c. As x increases, so does y. Y is almost not quite equal to 3x-2. In fact, it is greater, so I'd go with A. I'm pretty confident.

Kim and Sam were each given the same pair of numbers. Sam's description of the two numbers was: The larger number is 3 more than
irina1246 [14]

Answer:

Sam's description = 3x+3, Kim's description =  5x-7

Step-by-step explanation:

Given:

Kim and Sam were each given the same pair of numbers.

Sam's description of the two numbers was:

The larger number is 3 more than three times the smaller number.

Kim's description of the two numbers was:

Five times the smaller number decreased by 7 is the larger number.

Question asked:

Which equation represents the situation?

<u>Solution:</u>

Let smaller number = x

According to Sam's description of the two numbers, the equation will be:-

Larger number = 3 more than three times the smaller number

                         = 3x+3\ (eq1)

According to Kim's description of the two numbers was, the equation will be:-

Larger number = Five times  decreased by 7

                         = 5x-7\ (eq2)

By equating  both equation:-

5x-7=3x+3\\ \\ Subtracting\ both\ sides\ by \ 3x\\ \\ 5x-3x-7=3x-3x+3\\ \\ 2x-7=3\\ \\ Adding\ both\ sides\ by\ 7\\ \\ 2x-7+7=3+7\\ \\ 2x=10\\ \\ Dividing\ both\ sides\ by\ 2\\  \\ x=5

Smaller number = x = 5

Larger number = 3\times5+3=15+3=18

Therefore, equations represents the situation are 3x+3 and 5x-7

Find the length of AB.<br><br> please help!!
mr Goodwill [35]

Answer:

8.6 is the answer

Step-by-step explanation:

A = (3,9)

B = (8,2)

d² = (8-3)² + (2-9)²

or, d² = 5² + (-7)²

or, d² = 25 + 49

or, d² = 74

d = 8.6
