Amy and april are twin sisters they have a total of 120 cds if amy has twice as many cds has april how many cds does each twin have

The size of CD "sets" can be found by dividing the 120 CDs they have by 3 (Amy has two "sets" and April has one "set"). 120 divided by 3 gives you 40 per "set," and because Amy has twice as many CDs, she will have twice as many "sets," or 80 CDs, while April has 40.

9.8? i'm not really sure

Idon't see any graph, however the graph of the function : f(x) = x²-2x+3 is a parabola: 1) open upward (since a> 0)2) it intersects y-axis in 3 (y=3)3) its axis of symmetry is x = +1 ( -b/2a)4) it's minimum is y = -2, so its vertex is (1,-2)5) it doesn't intersect the x-axis since discriminant < 0
