The area of a square depends on the length of its sides. Answer the questions below regarding the relationship between the area of the square and the length of one side
of the square.

The independent variable, x, represents the length of one side of the square, and the dependent variable is the the area of the square, because the the area of the square depends on the length of one side of the square.

A function relating these variables is D(x) = x^2.

So D(6) =36, meaning if 6 is the length of one side then 36 would be the area of the square.

Step-by-step explanation:

The question clearly stated that the area depends on the side length, making the side length the independent variable.

The formula for the area of a square is the side length squared.

Have a good day :)

3.4 pizzas

step-by-step explanation:

given is a scatter plot showing number of pizzas sold during weeks for different issues of coupon

y represents number of pizzas sold and x number of coupons issued

y is marked verticaly and x horizontally

the trend line is given as

y =3.4x+43

this says that even when no coupon is issued pizzas sold will be 43

and rate of change of pizza sold for 1 unit of coupon = slope = 3.4

i.e. when x increases by 1 unit y increases by 3.4 units

hence for each additional coupon issued 3.4 pizzas more will be sold
