Answer:

First you can just flip the line on point C to make a 90 degree angle. That's the simple way.

Other way is to get the slope of AB let's say ex : -1/2

We need to get the slope of C to be a reversed reciprocal of -1/2. So, 2.

Basically I flipped -1/2 in to -2/1 then removed the negative sign for 2.

Hope that makes sense to ya

Find the distance between points P(8,1) and Q(1,6) to the nearest tenth
Ronch [10]
1 - 8 = - 7
6 - 1 = 5

Let us use the Pythagorean theorem:

c^2 = (-7)^2 + 5^2 = 49 + 25 = 74 -> c = 8.6

Show how to solve 2x+5=13, justify the steps
liberstina [14]

Answer:

The answer is 4

Step-by-step explanation:

2x + 5 = 13

Now, Subtract 5 from both side we get,

2x + 5 - 5 = 13 - 5

2x = 8

Then, Divide both side by 2 we get,

2x/2 = 8/2

x = 4

Thus, The answer is 4

In a race in which eleven automobiles are entered and there are no ties, in how many ways can the first three finishers come in?
viva [34]

Answer:

990 ways

Step-by-step explanation:

The total number of automobiles we have is 11.

Now, what this means is that for the first position , we shall be selecting 1 out of 11 automobiles, this can be done in 11 ways( 11C1 = 11!/(11-1)!1! = 11!/10!1! = 11 ways)

For the second position, since we have the first position already, the number of ways we can select the second position is selecting 1 out of available 10 and that can be done in 10 ways(10C1 ways = 10!9!1! = 10 ways)

For the third position, we have 9 automobiles and we want to select 1, this can be done in 9 ways(9C1 ways = 9!/8!1! = 9 ways)

Thus, the total number of ways the first three finishers come in = 11 * 10 * 9 = 990 ways
