The alpha airline company allows passengers two bags with a total weight of 100 pounds.
The equation is x+y=100
1.)What is the independent and dependent variable
2.) What is the slope
3.) What is the domain and range
4.) what is the x and y

See the explanation.

Step-by-step explanation:

1)

Anyone of the x and y is independent variable and the other one is dependent variable.

2)

The equation is x+y=100 or, y = 100 - x.

If we compare the above equation with y = mx + c, then m = -1.

The slope is -1.

3)

Both the domain and range is 0 to 100.

The weight of the bags can not be negative.

The highest weight of one bag can be 100.

Hence, the values will vary between 0 to 100.

4)

X and y are the weight of the bags.

answer: city needs 2.4 inches of rainfall more to match the record of 40 inches.

step-by-step explanation:

since we have given that

total annual rainfall a city record = 40 inches

this year, total rainfall recorded = 37.6 inches

number of inches of rainfall   is needed to match the record of 40 inches is given by

hence, city needs 2.4 inches of rainfall more to match the record of 40 inches.
