x=0.22222222...10x= 2.222222...10x-x=9x=2x=2/9=0.2222222...x=2/9
log2(x + 3) + log2(x - 3) = 4log2 [(x + 3)(x - 3)] = 4x^2 - 9 = 16x^2 = 25x = 5
Y= mx + cFinding m : change in y/ change in x => (8--7)/(3--2) = 3Finding c : input a pair of coordinates => 8 = (3 x 3) + c .... c = -1y = 3x -1
The event should be; mutually exclusive from the other outcome, independent from the other outcome (so its probability doesn't change ) and happen within a ...
Because its hypothetical inverse would be 'one to many' which is not a function. This is because a single x-value would map to several y-values at the same time.
