What is the series using summation notation? 36+69+102++267

first term =36

second term=69

So common difference=69-36=33

checking. 69+33=102

36=3+33

so the series in AP Becomes as...

(3+33) ,(36+33) ,(36+2(33)) ... (36+7(33))

So The Answer is...

(refer above attachment.)

Hope it helps...

walter needs to make at least 5 more cookies but no more than 40. 5 ≤ x ≤ 40

step-by-step explanation:

20 ≤ x + 15 ≤ 55

subtract 15 from all parts

20-15 ≤ x + 15-15 ≤ 55-15

5 ≤ x ≤ 40

this means how many more cookies he has to make

walter needs to make at least 5 more cookies, but no more than 40 cookies; 5 ≤ x ≤ 40

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.
