Answer:A, B and D

Step-by-step explanation:

A linear relationship is one in which when the variables are plotted, the graph would be a straight line. In a linear relationship, the highest power of the variables is 1. We would compare each of the given relations.

A) Double x and subtract five to get y. This is expressed as

2x - 5. It is a linear relationship.

B) Multiply x and y to get 20. This is expressed as

xy = 20. It is a linear relationship.

C) Multiply x times itself and add five to get y. This is expressed as

x^2 = y. It is not a linear relationship. The highest power of the variables is 2

D)Divide 40 by x to get y. This is expressed as

40/x = y. It is a linear relationship.

How tall is the flag pole (please give explanation too)
Tpy6a [65]

Answer:

  22 3/4 ft

Step-by-step explanation:

The diagram seems to show a 6 1/2 ft person casting a 9 ft shadow at the same time a flagpole is casting a 31 1/2 ft shadow. You want the height of the flagpole.

<h3>Proportion</h3>

Shadow lengths are presumed proportional to the height of the object making them. This means ...

  h/(31 1/2) = (6 1/2)/9 . . . . . all lengths in feet

Multiplying by 31 1/2, we get ...

  h = (31 1/2)(6 1/2)/9 = (819/4)/9 = 91/4

  h = 22 3/4 . . . . ft

The flagpole is 22 3/4 feet tall.
