Answer:

Option 2) When the x-value is 0, the y-value is 1.

Step-by-step explanation:

A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form y/x=k or y=kx

In a proportional relationship the constant of proportionality k is equal to the slope m of the line <em>and the line passes through the origin </em>

Remember that in a direct variation

For x=0, the value of y is equal to zero too

therefore

The graph is not a direct variation , because

When the x-value is 0, the y-value is 1.

<u>Given</u>:

The vertices of the quadrilateral WXYZ are W(2,4), X(4,2), Y(2,1) and Z(0,2)

The graph is rotated 90° about the origin.

We need to determine the coordinates of the quadrilateral W'X'Y'Z'

<u>Coordinates of the quadrilateral W'X'Y'Z':</u>

The rule to transform the coordinates 90° counter clockwise about the origin is given by

(x, y) \implies(-y, x)

Let us substitute the coordinates.

The coordinates of W' is given by

W(2,4)\implies W'(-4,2)

The coordinates of X' is given by

X(4,2) \implies X'(-2,4)

The coordinates of Y' is given by

Y(2,1) \implies Y'(-1,2)

The coordinates of Z' is given by

Z(0,2) \implies Z'(-2,0)

Therefore, the coordinates of the vertices W', X', Y' and Z' are (-4,2), (-2,4), (-1,2) and (-2,0) respectively.

Elena L [17]

Answer: $1,842

Step-by-step explanation:

John wants to earn 25% of his investment of $50,000 which is:

= 25% * 50,000

= $12,500

He has expenses of $9,600 yearly so the rent he should charge per year in order to make his 25% requirement as income is:

= Expenses + Return

= 9,600 + 12,500

= $22,100

Rent per month is:

= 22,100 / 12

= $1,842
