Question

solve:- 3x+1 / 2x-3= 2​

Answer 1

Step-by-step explanation:

we have to solve for x = ?

solution :-

as shown in attachment

here

we get

equation

x² +7x = 0

now

solving equation we get

x(x+7) = 0

=> x=0 and x+7= 0

=> x= 0 and -7 answer

Answer 2

Answer:

Acceleration ,a = -10m/s² (opposite direction of motion)

Final velocity ,v = 0m/s

Time taken ,t = 5s

To Find:-

Distance covered by the car before coming to rest ,s

Solution:-

⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀According to the Question

Firstly we calculate the initial velocity of the car . Using 1st equation of motion

v = u + at

where,

v is the final velocity

a is the acceleration

u is the initial velocity

t is the time taken

Substitute the value we get

:\implies:⟹ 0 = u + (-10) × 5

:\implies:⟹ -u = -50m/s

:\implies:⟹ u = 50m/s

So the initial velocity of the car is 50m/s

Now, calculating the final velocity of the car by using 3rd equation of motion.

v² = u² + 2as
