Using the dot plot for the hours students spend watching TV, where do you think the center of the data is? Explain how you found your answer.
Find all positive values for K for which each of the following can be factored. x^2 + x - k I don't even know where to begin on this one! By trial and error, I came up with -2 and -6. Are those right? Are there others?
Find the values of the polynomial for the given values of the variable. -x2-5x-6 x=-3 x=-2 I got 0 for the first one and 0 for the second. Am I figuring them wrong? (and that is an x squared, not 2x) -(-3)^2 -5(-3)-6 -(9)+15-6=0 Thanks! you are right in both cases -x^2-5x-6...
