A coffee shop owner would like to create a blend of cinnamon and hazelnut flavored Effee that sells for $8.00 a pound. Currently, the cinnamon coffee sells for $6.00 per pound and the hazelnut coffee sells for $9.00 per pound. Which of the following systems of equations could be used to determine the amount c, in pounds, of the cinnamon flavored coffee, and the amount h. in pounds, of the hazelnut flavored coffee that should be mixed to obtain 20 pounds of the desired blend?

r and t.

both are 64 degrees.

the 8 in 8,420 is in the thousands place so it's value is 8 thousand.

the 8 in 6,870 is in the hundreds place so it's value is 8 hundred.

divide 8000 by 800 to find the answer:

8000 / 800 = 10

the 8 in 8,420 is 10 times greater than the 8 in 6,870

sample answer: you can determine whether each element of the domain is paired with exactly one element of the range. for example, if given a graph, you could use the vertical line test; if a vertical line intersects the graph more than once, then the relation that the graph represents is not a function.
