H. C.F of 9x2 – 4y2 – 8yz – 4z2, 4z2 - 4y2 - 9x2 - 12xy and 9x2 + 12xz + 4z2 - 4y2

Solve by any method (graphing, substitution or linear combination)y = x - 82x + 3y = 1a) (2, -6)b) (5, -3)c) (4, -4)d) (0, -8)i figured it out. the answer is (5, -3)

What is the range for 31,39,29,34,37,24,36,33,34,28

Graph g(x)=2cosx . use 3.14 for π . use the sine tool to graph the function. graph the function by plotting two points. the first point must be on the midline and closest to the origin. the second point must be a maximum or minimum value on the graph closest to the first point.
