Emergency! if a = 1, find the values of b, c, and d that make the given expression equivalent to the expression below. expression given: (3x^(2)+2x-21)/(-2x^(2)-2x+12)*(2x^ (3)+25x+63)/(6x^(2)+7x-49) expression that need to equal to the given one: (ax + b) / (cx + d) a= 1

Recall that the owner of a local health food store recently started a new ad campaign to attract more business and wants to know if average daily sales have increased. historically average daily sales were approximately $2,700. the upper bound of the 95% range of likely sample means for this one-sided test is approximately $2,843.44. if the owner took a random sample of forty-five days and found that daily average sales were now $2,984, what can she conclude at the 95% confidence level?

Gabriel determined that his total cost would be represented by 2.5x + 2y – 2. his sister states that the expression should be x + x + 0.5x + y + y – 2. who is correct? explain.

Ineed big ! the cost of a school banquet is $25 plus $15 for each person attending. create a table, sketch the graph, and write an equation in slope-intercept and point-slope form that gives total cost as a function of the number of people attending. what is the cost for 77 people?
