Luke is having a rectangular swimming pool built in his back yard. he wants it to be 30 feet longer than it is wide. he also has to
decide how deep he wants the pool to be. he wants the width of the pool to be at least 15 feet greater than the depth.
the cost of the pool will be based on the depth and area of the pool. the cost of the pool will be $10 per square foot of perimeter
plus $30 per foot of depth. luke can afford to spend no more than $15,000 on the construction of the pool.
create a sustem of inequalities to model the situation above, and use it to determine how many of the solutions are viable.

What is x and y (use substitution? ) 5x+3y=38 and y=3x+8?

Analyze the data sets below. data set a 25,25,25,26,26,26,27,28,28,29,30,31,31,32,33,33,34,35,35,35 data set b 25,25,25,26,26,26,26,27,27,27,27,28,28,29,29,30,31,31,32,34 which of the following statement are true? select all that apply. a. data set a is relatively symmetric and data set b is skewed left. b.the means of the data sets are within 3 units from eachother. c.the data sets have the same standard deviation. d.the mean of data set a is 27.95 and the mean of data set b is 30. e. the data set b has a higher standard deviation than data set a. f. the mean and median of data set a are close in value.

For the inequality |c| < |d| to be true, which of the following must be true?
