Which graph shows the equation V = 4 + 2t, where V is the total volume of water in a bucket and t is the elapsed time in minutes?

On a coordinate plane, the x-axis shows elapsed time in minutes (t) and the y-axis shows total volume of water (V). A straight line with a positive slope begins at point (0, 3) and ends at point (5.5, 24).

On a coordinate plane, the x-axis shows elapsed time in minutes (t) and the y-axis shows total volume of water (V). Solid circles are at points (0, 3), (1, 6), (2, 10), (3, 14), (4, 18), (5, 22).

Peaches are being sold for $2 per pound.The customer created a model to represent the total cost of peaches bought. If x represents the number of pounds of peaches bought and y represents the total cost of the peaches, which best describes the values of x and y?

The values of both x and y can be any real number.

The values of both x and y will be real numbers greater than or equal to 0.

The value of x and y will always be zero

The value of x can be any real number greater than or equal to 0, but the value of y must be an integer greater than or equal to 0.

To bill customers for water usage, one city converts the number of gallons used into units. This relationship is represented by the equation u = 748g, where g is the total number of gallons of water used and u is the number of units. Determine which statements about the relationship are true. Choose two options.g is the dependent variable.u is the dependent variable.g is the independent variable.u is the independent variable.The two variables cannot be labeled as independent or dependent without a table of values.

g is the dependent variable.

u is the dependent variable.

g is the independent variable.

u is the independent variable.

The two variables cannot be labeled as independent or dependent without a table of values.

Which statements apply to the ratio of rice and water? Choose two options.

The amount of rice is the dependent value.

The amount of water is the dependent value.

The amount of rice is the independent value.

The amount of water is the independent value.

The values cannot be labeled as dependent or independent without a given equation.

A mapping diagram showing a relation, using arrows, between input and output for the following ordered pairs: (negative 3, negative 9), (2, negative 6), (negative 5, 4), (1, 2), (6, 0).

{x | x = –5, –3, 1, 2, 6}

{y | y = –9, –6, 0, 2, 4}

{x | x = –9, –6, –5, –3, 0, 1, 2, 4, 6}

{y | y = –9, –6, –5, –3, 0, 1, 2, 4, 6}
