Answer:
x=10
y=5
Step-by-step explanation:
Plugin 2y for x in the first equation.
you will get -4(2y)+11y=15
then you have -8y+11y=15
3y=15
y=5
x=2y, so x=10
It’s the first one! The table shows X going up and Y going down, so the slope would be negative!
Answer: True
Explanation:
ABCD is a face on the figure
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.
