12x+9−3x−4 Identify the LIKE TERMS in the expression. If there are multiple groups of like terms, use one answer space per group. If there is only one group of like terms, type NONE in the second space.

like terms are 12x and -3x, 9 and -4.

Step-by-step explanation:

12x and -3 have a variable of x. 9 and -4 are constants. Since they are like terms you can group them to be 9x+5. 12x-3x is 9x and 9-4 is 5.

a function could be identified in 3 ways either on a chart,graph, or ordered pairs. first a function is that each point has its own. the rule is that there can be many x's to one y but there can not be 2 x's at different y's. so on a graph when you put a straight line through the y's there should be one dot only to be a function.

step-by-step explanation:

the square root of what number? if you add that, then someone will probably answer the question.
