y=4
Step-by-step explanation:
4y+3=19
=4y=19-3
=y=16/4=4
Answer:
its a function
slope form:y+5=-1.18·(x-3)
(-2.5,1.5)
Step-by-step explanation:
Step-by-step explanation:
The displacement of a particle d (in km) as a function of time t (in hours) is given by :

Displacement at t = 4 hours,

Velocity of particle is given by :

Velocity at t = 4 hours,

Acceleration of the particle is given by :

At t = 4 hours,

Therefore, the displacement, velocity and acceleration at t = 4 hours is 205 km, 136 km/h and 58 km/h² respectively.
Answer:
25
Step-by-step explanation:
As the triangles within the bigger triangle are similar, the sides are in proportion.
⇒ 
⇒ 
⇒ 3w = 75
⇒ w = 25
