Answer: x^2-2x-35=0

Step-by-step explanation: so we know the solutions are -5 and 7 and we have x^2+___+___=0. So the roots are ( x- (-5)) (x-7). -( -5+7) = -2 and (-5)(7)= -35. So now we have x^2+-2+-35=0. So the answer is x^2-2x-35=0

Answer:

Equation: 10 - 15 = -5. 14 - 7 = 7.

Step-by-step explanation:

1. For the first part you would take an additional five away from the ten so that way you would go into the negatives.

2. For the second part all you have to do is subtract seven from fourteen, and you'll get seven.

Hope this answer helped you!

Which table represents the same rebellion as the set {(-6,4) ,(-4,0) ,(-3,2) ,(-1,2)}
alina1380 [7]
I think you meant to say "relation" instead of "rebellion"? I'm not sure. Anyways, all you're looking for is the table with the x values -6, -4, -3, -1 which pair up with the y values 4, 0, 2, 2 in that exact order.

Table B does this exactly. The first row represents x = -6, y = 4. The second row represents x = -4, y = 0. The third row represents x = -3, y = 2. The fourth row represents x = -1, y = 2.

Answer: Choice B
