Answer:7g=21
Step-by-step explanation:
Answer:
y = 4
Step-by-step explanation:
5x + y = -1
y = -1 - 5x
y = 6x + 10
6x + 10 = -1 - 5x
11x = -11
x = -1
y = 6x + 10 = 6(-1) + 10 = -6 + 10 = 4

Answer:
2nd car is running faster than the first car by 2.01 units.
Step-by-step explanation:
Let's assume that
- the velocity of first car,
![v_1\ =\ 20i\ +\ 25j](https://tex.z-dn.net/?f=v_1%5C%20%3D%5C%2020i%5C%20%2B%5C%2025j)
- and the velocity of second car
![v_2\ =\ 30i](https://tex.z-dn.net/?f=v_2%5C%20%3D%5C%2030i)
=> speed of first car,
![u_1\ =\ \sqrt{(20)^2+(25)^2}](https://tex.z-dn.net/?f=u_1%5C%20%3D%5C%20%5Csqrt%7B%2820%29%5E2%2B%2825%29%5E2%7D)
![=\ \sqrt{400+625}](https://tex.z-dn.net/?f=%3D%5C%20%5Csqrt%7B400%2B625%7D)
![=\ \sqrt{1025}](https://tex.z-dn.net/?f=%3D%5C%20%5Csqrt%7B1025%7D)
= 32.01 units
and speed of second car,
![u_2\ =\ \sqrt{(30)^2+(0)^2}](https://tex.z-dn.net/?f=u_2%5C%20%3D%5C%20%5Csqrt%7B%2830%29%5E2%2B%280%29%5E2%7D)
= 30 units
![u_2\ -\ u_1\ =\ 32.01\ -30](https://tex.z-dn.net/?f=u_2%5C%20-%5C%20u_1%5C%20%3D%5C%2032.01%5C%20-30)
= 2.01 units
Hence, 2nd car is running faster than the first car by 2.01 units.
Bro... ahahaha the answer is D DDDDDDDDDDDDDDD peace man
