Answer:
The answer is D.
Step-by-step explanation:
We have to apply Discriminant Law. When a quadratic equation, ax² + bx + c = 0 has equal roots so the discriminant will be 0. Then, you have to substitute the values into the formula :
Answer:
B and D
Step-by-step explanation:
(2x-6):(6x-4)
you can divide everything by 2
2x÷2=x, -6÷2=-3
6x÷2=3x, -4÷2=-2
so it's B X-3:3x-2
(2x-6):(6x-4)
multiply everything by 2
2x × 2 = 2x, -6 × 2 = -12
6x × 2 = 12x, -4 × 2 = -8
so it's D (4x-12): (12x-8)
x=adult tickets
y=student tickets
(9x+13y=212)*4= 36x+52y=848
(4X+15y=168)*9= 36x+135y=1512
subtract both equations -83y=-664
divide by -83 y=8
student tickets cost $8
There is 100 N pushing the box to the right and 10 N pushing the box to the left
since there is force being applied in opposite directions, the net force is found by subtracting the 2
100 - 10 = 90 N ( Net Force)
and because the higher force is pushing the box to the right, the direction will accelerate to the right.
