Answer:
a) -10 b) 7
Step-by-step explanation:
a) 2(x+ 3) = x - 4
2x + 6 = x - 4
2x - x = -6 - 4
x = -10
b) 4(5x - 2) = 2(9x + 3)
20x - 8 = 18x + 6
20x - 18x = 6 + 8
2x = 14
x = 14/2
x = 7
Answer: The potential energy decreases and the kinetic energy increases
Step-by-step explanation:
When a body is at rest , the Potential energy is maximum because the body is not moving and the acceleration is therefore zero but as soon as the body starts moving , it will convert the potential energy to kinetic energy , therefore the kinetic energy will therefore increase.
Answer:
Piece one would equal to 14" and piece two would be 42" because 42 is three times the length of 14
If the line is parallel to y=-x+4, the line must have the same slope.
So, the slope of your line is -1.
Now we need to find the y intercept. We should use the point given.
y=mx+b
0=-1(5)+b
b=5
Equation: y=-x+5
