NemiM [27]

Answer:

$\boxed{2x-3}$

Step-by-step explanation:

$f(x)=3x-1\\ g(x)= x+2$

$(f-g)(x)\\f(x)-g(x)$

$(3x-1)-(x+2)\\ 3x-1-x-2\\2x-3$

If CD has endpoints (–3, 4) and (5, 2), what are the coordinates of its midpoint?

Aleks [24]

You can read it of the graph which is (1,3) or also calculate it with vectors:

calculate the vector CD:
(5-(-3),2-4)=(8,-2)
to calculate the midpoint you need half of the vector length:
(8,-2)/2=(4,-1)
add the vector to C:
(-3,4)+(4,-1)=(1,3)=midpoint of CD

so it's the third option

A 100 foot rope weighs 200 pounds. It is hanging vertically from the top of a tall building. After "x" feet have already been li

Levart [38]

Answer:

2*(100-X)

Step-by-step explanation:

Total length = 100 ft

Total weight =200 pounds

Assuming that the rope has an uniformly distributed weight, its weight per feet is:

$W_f = \frac{200}{100} =2\ lbs/ft$

If "x" feet have already been lifted, the length left to be lifted is 100 - x.

Therefore, the weight of the remainder of the rope is:

$W=2*(100-X)$
