3. A 0.200 kg air-track glider moving at 1.20 m/s bumps into a 0.600 kg glider at rest.
(a) Find the total kinetic energy after collision if the collision is elastic.
(b) Find the total kinetic energy after collision if the collision is completely inelastic.

check above link.

graphically?   well, you graph them both, the solutions is where they both intersect each other, since there are two solutions, meaning they will meet twice, or namely the linear will run into the quadratic curve twice, and where they meet, those x,y coordinates are the solutions to the system.

actually your concept is wrong

step-by-step explanation:

150% of x =300

150x=300×100

x=(300×100)÷150

x=200

answer: it is a.,b.,d.

step-by-step explanation:

for this case we must apply distributive property to the following expression:

the distributive property states that:

then, when applying the property we have to multiply the -2 for each term within the parenthesis:
