Answer:
D. The input force is equal to the output force
Step-by-step explanation:
A pulley changes the direction of the applied force, but does not change its magnitude. The mechanical advantage is the ratio of output force to input force, so must be 1 when the force magnitude does not change.
Answer:
y = -2x + 6
Step-by-step explanation:
Slope = (-4 - 8)/(5 + 1)
= -12/6
= -2
Equation
y - 8 = -2(x + 1)
y - 8 = -2x - 2
y = -2x + 6 <-----------slope-intercept form
Using slip and slide
2x^2+7x+6
x^2+7x+12
(x+3)(x+4)
(2x+3)(x+2)
The best answer is none of the above.
When foiling the answer choices,
A: 2x^2+10x+8
B: 2x^2+8x+6
C: 2x^2+5x+3
D: 4x^2+10x+6
