Answer:

(1, -2)

Step-by-step explanation:

Subtracting the first equation from the second gives ...

(5x +y) -(3x +y) = (3) -(1)

2x = 2 . . . . . collect terms

x = 1 . . . . . . . divide by 2

Then substituting into the first equation, we have ...

3·1 +y = 1

y = -2 . . . . . . subtract 3

The solution is (x, y) = (1, -2).

To find average monthly income, multiply the net pay by the number of pay periods per year. Then divide this yearly income by 12

vladimir2022 [97]

True. To find average monthly income, multiply the net pay by the number of pay periods per year. Then, divide this yearly income by 12 months.

For example:
Daily wages:
Daily wages * 365 days = Total Wage
Total wage / 12 months = average monthly income

Weekly wages:
Weekly wages * 52 weeks = total wage
total wage / 12 months = average monthly income

A group of neighbors are constructing a community garden that is 80 m wide and 40 m long the top to vertex are plotted below at

Ainat [17]

Question Correction

A group of neighbors are constructing a community garden that is 80 meters wide and 40 meters long. The top two vertices are plotted below at (10, 70) and (90, 70). What are the coordinates for the bottom two vertices of the garden?

Answer:

(10,30) and (90,30)

Step-by-step explanation:

The community garden is 80 m wide and 40 m long.

The top two vertex are plotted at: (10, 70) and (90, 70).

Horizontal Distance =90-10=80

This serves as the Width of the garden.

Since the length is 40m, the bottom two vertex can be derived by the transformation: (x,y-40).

(x,y-40)-->(10, 70)=(10,30); and

(x,y-40)-->(90, 70)=(90,30)

The coordinates for the two bottom vertices are (10,30) and (90,30).
