Busby County is rectangular. A map of the county on a coordinate plane shows the vertices of the county at A (-4,6), B (6,6), C (6,-9), and D -4,-9). Each unit on the map represents 1 mile.
What is the county's perimeter?
The

the correct answer is a.) bc< mn 5 stars if this you : )

step-by-step explanation:

this is a direct variation proportion. y = kx

y is the total amount due, k is the constant of variation, and x is the number of texts sent.

plug in the 3.20 and the 16 to solve for the "k". this is the constant of proportionality. it is the value that will not change.

3.20 = k(16). solving you get $.20 per text.

the equation would then be y = .20x
