D=-16t^2-4t+382 What is the answer to this? Please help!!!!

CaHeK987 [17]

D equals 38.2 I think because t equals 9.55. You would add -16t with -4t and get -20t. Which would turn into D=-20t^2+382. Since you can't multiply 2 with -20t, you would divide it by 382 which would be 191. D=-20t+191 with this, you would subtract 191 from +191 which would cancel out and it would turn the problem into -191=-20t. You would divide -20 from itself and -191 and get t=9.55. Then you plug t where it was in the problem and then you get that D=38.2. I hope my answer is right and it helps you.

Y=x-7<br> 6x-6y=-7<br><br> elimination method

Archy [21]

Answer:

The system has no solutions.

Step-by-step explanation:

Let's write it in a more traditional form

$\left \{ {{x-y=7} \atop {6x-6y=-7}} \right. \\$

Try staring at it for a bit, and then realize what you are being asked: find two numbers whose difference is - at the same time, 7, and -7/6. That's impossible.

Same result you get by elimination. Multiply the first by 6 and either add or subtract - your choice the second. In either case you will get 0 = 35 or 0=49, which are obviously absurd
