For each term below, identify the coefficient and the variable. A.) 6r coefficient variable

B.) 20n coefficient variable

C.) y coefficient variable

D.) 9trx coefficient variable

A.) 6r    

coefficient = 6

variable = r  

B.) 20n

coeffect = 20

variable = n  

C.) y

coefficient = 1

variable = y  

D.) 9trx

coefficient = 9

variable = t, r, and x

Step-by-step explanation:

Coefficient = represented by a number

Variable = represented by a letter

For the third one y is the same as 1y therefore y has a coefficient of 1

answer: translate the circles so they share a common center point and dilate circle y by a scale factor of 3.

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.
