The coordinates of the vertices of quadrilateral hijo are h(1,4) I(3,2) j(-1,-4) k(-3,-2) if quadrilateral hijo is rotated 270° about the origin what are the vertices of the resulting image quadrilateral h I j k

If the graphs of the linear equations in a system are parallel, what does that mean about the possible solution(s) of the system? a. there are infinitely many solutions. b. there is no solution. c. there is exactly one solution. d. the lines in a system cannot be parallel.

Adecibel is a logarithmic unit that can be used to measure the intensity of a sound. the function y = 10logx gives the intensity of a sound in decibels, where x is the ratio of the intensity of the sound to a reference intensity. the reference intensity is generally set at the threshold of hearing. use the graphing utility to graph the decibel function. a whisper has a sound intensity of 30 decibels. use your graph to you complete the following statement. the sound intensity of a whisper is times the reference intensity.

Use the quadratic function to predict f(x) if x equals 8. f(x) = 25x2 − 28x + 585
