Suppose you are writing a report that compares the average monthly temperatures over the course of one year between two sunbelt states. which visual aid would most clearly support your purpose?

A graph or chart.

A chart (also known as a graph) that contains information about the two states' temperatures would be the most useful visual aid in this case.

A chart is a representation of data in which the information is shown through symbols such as bars, lines or slices of a pie. It is used to organize numerical data and to make it easier for people to understand large quantities of data.

x=4, y=4

step-by-step explanation:

y=2x-4;

x+2y=12

we can use substitution since the first equation is solved for y

where ever you see y in the second equation, replace it with 2x-4

x + 2(2x-4) = 12

distribute the 2

x+4x-8 = 12

combine like terms

5x-8=12

add 8 to each side

5x-8+8=12+8

5x=20

divide by 5

5x/5 = 20/5

x =4

we still need to solve for y

y = 2x-4

we know x =4

y = 2(4) -4

y = 8-4

y=4
