anonymous

Best ResponseYou've already chosen the best response.0ok i so take what you wrote, copy and paste it directly in to wolfram

anonymous

Best ResponseYou've already chosen the best response.0yeah i did that and got (4z  3)/(x + 2)

anonymous

Best ResponseYou've already chosen the best response.0yeah i get that too, but of course with a z

anonymous

Best ResponseYou've already chosen the best response.0i could also show you how to do it without wolfram, it is "factor and cancel"

anonymous

Best ResponseYou've already chosen the best response.0oh yeah typo lol sorry okay i think it'll be better without wolframe alpha in case my teacher asks

anonymous

Best ResponseYou've already chosen the best response.0ok then here is the deal do you know how to factor?

anonymous

Best ResponseYou've already chosen the best response.0\[ (12z^2  25z + 12)=(4 z3) (3 z4)\] and \[(3z^2 + 2z  8)= (3 z4) (z+2)\]

anonymous
 one year ago
Best ResponseYou've already chosen the best response.0so \[\frac{12z^2+25z+12}{3z^2+2z8}=\frac{4z3)(3z4)}{(3z4)(z+2)}\]

anonymous

Best ResponseYou've already chosen the best response.0oh and then you cross out (3z  4)?

anonymous
 one year ago
Best ResponseYou've already chosen the best response.0there is a common factor top and bottom of \(3z4\) which cancels, you get \[\frac{(4z3)(3z4)}{(3z4)(z+2)}=\frac{4z3}{z+2}\]

anonymous

Best ResponseYou've already chosen the best response.0exactly what you said

anonymous

Best ResponseYou've already chosen the best response.0that is the idea of all of these factor and cancel

anonymous
 one year ago
Best ResponseYou've already chosen the best response.0okay cool i get it now

anonymous
 one year ago
Best ResponseYou've already chosen the best response.0as to how to factor, you are pretty much on your own, but you can use wolfram to do it for sure

anonymous
 one year ago
Best ResponseYou've already chosen the best response.0and you can use wolfram to give the final answer too, but once you have it factored it is easy to cancel

Best ResponseYou've already chosen the best response.0Bob and Susie wash cars for extra money over the summer. Bob's income is determined by f(x) = 6x + 13, where x is the number of hours. Susie's income is g(x) = 4x + 18. If Bob and Susie were to combine their efforts, their income would be h(x) = f(x) + g(x). Assume Bob works 3 hours. Create the function h(x) and indicate if Bob will make more money working alone or by teaming with Susie. h(x) = 2x + 5, work alone h(x) = 2x + 5, team with Susie h(x) = 10x + 31, team with Susie h(x) = 10x + 31, work alone

Best ResponseYou've already chosen the best response.0there is one change in sign of the coefficients, which is a fancy way of saying that the go "minus, minus, minus, minus , PLUS" only once change in sign therefore there is one positive zero there cannot be no positive zeros because you count down by twos
