Larissa decided to build a kite using a new set of materials called Systekite. The challenge with the new material is that all dimensions are expressed algebraically. According to the instructions: AB = 2x + 3y + 4
AC = 4x + 2y - 1
BD = x - 2y + 7
CD = 2x - y - 3
m∡A = 3x + 2y + 15
m∡D = 5x - 2y + 27

What values of x satisfy the inequality x^2-9x< 0? how is your answer shown on the graph?

What are the coordinates of the midpoint of ab? ,1/2) /2,-1) ,-3/2) /2,-2)

Apsychology student wishes to investigate differences in political opinions between business majors and political science majors at her college. she randomly selects 100 students from the 260 business majors and 100 students from the 180 political science majors. does this sampling plan result in a simple random sample? why or why not? no, because each group of 200 students in the sample does not have the same chance of being selected. yes, because each group of 200 students in the sample has the same chance of being selected. no, because each individual student does not have an equal chance of being selected. yes, because each individual student has the same chance of being selected.
