−(x+2y−4z)

=−x−2y+4z




0.5(4x+3y−8z)

=(0.5)(4x+3y+−8z)

=(0.5)(4x)+(0.5)(3y)+(0.5)(−8z)

=2x+1.5y−4z

-(x+2y-4z)= -x-2y+4z\\\\0.5 (4x+3y-8z)= 2x+1.5y-4z\\\\\sf Using~ the~ formulas: -(a-b)=-a+b\\ and~ a (b+c)=ab+ac

the time required to assemble computers varies directly as the number of computers assembled and inversely as the number of work
olga2289 [7]

Answer:

16 hours

Step-by-step explanation:

let t be time, n the number of computers and w the number of workers, then

t = \frac{kn}{w} ← k is the constant of variation

To find k use the condition n = 30, w = 6 and t = 10 , then

10 = \frac{30k}{6} ( multiply both sides by 6 )

60 = 30k ( divide both sides by 30 )

2 = k

t = \frac{2n}{w} ← equation of variation

When w = 5 and n = 40 , then

t = \frac{2(40)}{5} = \frac{80}{5} = 16 hours

We will take the common terms in the expressions-

Here in the expression, 3y is a common term.
So,

6y - 15y^{2}

3y(2 - 5y)

So, the answer is 3y(2 -5y)

*LMK

*L-K=x+3

*L-M=6x-10

*M-K= 3x-3

L-M + M-K = 6x -10 + 3x -3 = 9x -13

10 and 11)

Both lines are horizontal

both lines consist of intervals due to having 2 points on one line making it a distance between 2 points.

they are also concurrent lines because more then 3 lines pass through one point

they are also intersecting lines because they cross over each other
