Another way to solve this is to use the Midpoint Formula. The midpoint of a segment joining points

and

is

So the midpoint of your segment is

Perhaps it helps to see that the x-coordinate of the midpoint is just the average of the x-coordinates of the points. Ditto for the y-coordinate of the midpoint; just average the y's.
Answer:

Step-by-step explanation:
Let's find our C value for the quadratic equation.

That is our C. Since we added 9 to one side, we have to do the same to the other. We get:

Now, lets form the left side as a binomial squared.

Let's square both sides now:

Now, we subtract 3 from both sides to isolate the variable, X:

This means that the answers are:

I do not understand your answers though. Answer A makes no sense, answer B is 221, answer C is 115, and answer D also does not make sense. If you could clarify this portion, maybe I can help you find your alphabetic answer
Answer:
50 27.5
50.01 27.5055
50.02 27.511
50.03 27.5165
Step-by-step explanation:
The sales price is 85% of the original $2,200, which can be calculated as follows: .85(2,200) = 1870 Assuming you meant 15% discount price..
Now we need to find a 7% sales tax, which can be calculated as follows:
.07(1870) = 130.90
Now we add the sale price and the sales tax: 1870 + 130,90 = $2000.90 for the total cost.
Answer:
20
Step-by-step explanation:
Area of one trapezoid is 10 so double that is 20
i think thats the answer im not 100% sure but i hope this helps :)
