I got an 8/12 cuz I listened to some idiot on here. The REAL ANSWERS are: 1- b 2- b 3- a 4- b 5- a 6- b 7- DIY 8- b 9- d 10- a 11- b 12- c TRUST ME YOUR WELCOME :3
Ahhh! That makes a lot more sense, thanks for the breakdown. I knew I was doing SOMETHING wrong haha. Thanks again :D
Thanks. My problem from there is figuring out how to factor it.. I have x^2+x-3=0. Theres no factors of -3 that add up to 1. -3+1 = -2 -1+3= 2 When i try to use the quadratic formula I end up with: (-1+/1(sqrt)13)/2 Am I missing something?
Ohhh! Thank you so much!
*facepalm* That tricked me. I think it's (152, 7316) & (0,20)? I guess ANY number times 0 is a factor of 0... So I did -152 x 0=0 and -152+0 = -152. That gave me (x-152)(x+0)
Ok.. I understand how to eliminate y and everything, then you factor it as normal. The solutions to that equation were (-1, 1) and (2,4). I'm working on another one and used the same steps. y=48x+20 -(y=-x^2+200x+20) and i ended up with : 0=x^2-152x This
Sorry :) I must've gotten something confused. I think I get it now. Thank you!
I understand how to do that, thats substitution. How can I solve it with elimination?
8>7n+1 8-1>7n+1-1 7>7n 1>n * You do not change the sign because you did not divide by a negative. You only change the sign when you do divide by a negative number.
