Agroup of adults and students went on a class trip to washington, dc. the number of male students was 1 more than 7 times the number of adults. the number of female students was half the number of male students. if the total number of people who went on the trip is 82, find the numbers of male students and female students.

Mr. walker gave his class the function f(x) = (x + 3)(x + 5). four students made a claim about the function. each student’s claim is below. jeremiah: the y-intercept is at (15, 0). lindsay: the x-intercepts are at (–3, 0) and (5, 0). stephen: the vertex is at (–4, –1). alexis: the midpoint between the x-intercepts is at (4, 0). which student’s claim about the function is correct?

Use set builder notation to represent the following set: { -3, -2, -1, 0}

For which pair of functions is (gof)(a)=|a|-2?
