If the Internet consisted of four computers, there would be six possible connections. If it consisted of five computers, there w
Luba_88 [7]

Answer:

<em>45 possible connections</em>

<em />

Step-by-step explanation:

The general equation for finding the possible number of connections in a network is given as

\frac{n*(n - 1)}{2}

where n is the number of computers on the network.

for 4 computers, we'll have

\frac{4*(4 - 1)}{2} = \frac{4*3}{2} = 6

for 5 computers, we'll have

\frac{5*(5 - 1)}{2} = \frac{5*4}{2} = 10.

therefore, for 10 computers, we will have

\frac{10*(10 - 1)}{2} = \frac{10*9}{2} = <em>45 possible connections</em>

Solve the system by the substitution method.
Ghella [55]

Answer:

A) The solution set is (6,-8).

Step-by-step explanation:

3x - y = 26

-3x       - 3x        Subtract 3x from both sides

-y = -3x + 26     Divide both sides by -1

y = 3x - 26

Now plug this into 7x + 8y = -22 to solve for x

7x + 8(3x - 26) = -22        Distribute

7x + 24x - 208 = -22       Combine like terms

31x - 208 = -22

     + 208    + 208            Add 208 to both sides

31x = 186                           Divide both sides by 31

x  = 6

Plug this into y = 3x - 26 to solve for y

y = 3(6) - 26           Multiply

y = 18 - 26              Subtract

y = -8

The lines below are perpendicular if the slope of the solid line is 4 what is the slope of the dashed line
const2013 [10]

Answer:

The slope of the dashed line is -\frac{1}{4}

Step-by-step explanation:

Perpendicular lines and slopes:

If two lines are perpendicular, the multiplication of their slopes is -1.

What is the slope of the dashed line

Perpendicular to a line with slope 4, so:

4m = -1

m = -\frac{1}{4}

The slope of the dashed line is -\frac{1}{4}
