⓵
Replace the w with it’s value in the equation :
w⒳ = -2x + 1
-7 = -2x + 1
⓶
Then, you just simplify the right side in order to isolate the x (always take in consideration your priorities of operation) :
-7 = -2x + 1
÷-2 ÷-2
3.5 = x + 1
-1 -1
2.5 = x ☻
Slope =( 4 - 0) /(-6 - 2) = 4/-8 = -1/2
<span>passes through the points (−6, 4) and (2, 0).
so
y - 0 = -1/2(x - 2)
y = -1/2 (x - 2) </span><span>

Answer:
0.4
Step-by-step explanation:
This is a physics problem.
The law is that the momentum is preserved: total momentum before collsion = total momentum after collision
Momentum before collision = 80 kg.m/s - 100 kg.m/s = -20 kg.m/s
Then answer is b. - 20 kg.m/s
