Answer:
y=8
Step-by-step explanation:
first you want to subtract 2y from 10y which will give you 8y and then divide both sides by 8 to get y alone and you will get y=8
Answer:
B. The statement does not make sense because a linear function has a straight-line graph.
Step-by-step explanation:
Linear functions have a general form y = m*x +b and only yield straight-line graphs. Therefore, the statement does not make sense, either the graphed function is not linear, or there was an error in the graphing process. The answer is alternative B.
*Note that alternative D is wrong because it is incomplete, since linear functions can have a rate of change that increases (m > 0), decreases (m < 0) or that is zero (m = 0).
Answer: 7x + 261
Step-by-step explanation:
(5x + 252 + x + 5) + (x + 4)
5x + 252 + x + 5 + x + 4 (get rid of parenthesis)
7x + 261 (combine like terms)
Would it be
(2r-7)*(2r+7)
