It’s A
Explanation / when you multiply 7 by -9 you get -63
1,643 bc of multiplying or 85 bc of adding but I'm pretty sure it's multiplying
The solution to the inequality is y < -12 ( y less than negative 12).
Step-by-step explanation:
Given inequality is;
y + 15 less-than 3
y+15<3
For solving the inequality, we will subtract 15 from both sides in order to find y.
Subtracting 15 from both sides of inequality
The solution to the inequality is y < -12 ( y less than negative 12).

Your answer would be C. x = 6, y = 5
This is because if you plug the numbers in to the inequality, we get:
(4 × 5) ≥ (3 × 6) + 2
20 ≥ 18 + 2
20 ≥ 20
which is correct.
I hope this helps!
Initially, Ball A of 10 kg will have velocity x, while Ball B of 30 kg has velocity -10 m/s.
After collision, Ball A will have a velocity of -30 m/s, while Ball B will have velocity 10 m/s. We assume their masses do not change.
(10 kg)(x m/s) + (30 kg)(-10 m/s) = (10 kg)(-30 m/s) + (30 kg)(10 m/s)
10x - 300 = -300 + 300
x = 30 m/s (to the right)
