Answer:

3 < y
y < -2

Step-by-step explanation:

1. -2y+7 < 1

Add 2y-1:

6 < 2y

Divide by 2:

3 < y

2. 4y +3 < -5

Subtract 3:

4y < -8

Divide by 4:

y < -2

_____

These are graphed on the number line with open circles because y=-2 and y=3 are not part of the solution set.

A bug splatters on the windshield of a moving car. Describe the 1. Forces 2. Impulses 3. Momentum changes 4. And accelerations o

uranmaximum [27]

Answer:

acceleration=force/mass

Due to variation in the mass[ as same force as per magnitude acts on both of them] the acceleration developed in the bug will be more and the acceleration developed in the car is negligible.

impulse=change in momentum

The impulse of bug is more and that of car is small.

momentum changes=change in momentum

force=change in momentum/time of contact

the force exerted by car on the bug will be more than the converse

Total. momentum is conserved , so magnitude of change in momemtum or impulse is same. By Newtons third law, since the bug have smaller mass, its change in magnitude of velocity is larger.
