Given ΔABC with A(–4, –2), B(4, 4), and C(18, –8), write the equation for the line containing median segment The term is line se
Monica [59]
Here we want to find the equation of the line containing the median CP.

P, being the midpoint of AB can be found using the midpoint formula as:

\displaystyle{ P=( \frac{-4+4}{2} ,  \frac{-2+4}{2} )=(0, 1).


The slope m of the line through CP can be found by the slope formula using points C(18, -8) and P(0, 1):

\displaystyle{ m= \frac{y_2-y_1}{x_2-x_1}= \frac{-8-1}{18-0}= \frac{-9}{18}= \frac{-1}{2}.


Now, we can write the equation of the line with slope -1/2, passing through
P(0, 1):

y-1= \frac{-1}{2}(x-0)\\\\y= -\frac{1}{2}x+1.


Answer: y=-\frac{1}{2}x+1

matrenka [14]

Answer:

Choice 1

Step-by-step explanation:

m^2 +n^2=13^2

m^2=13^2-n^2

n^2=13^2-m^2

Both m & n =(13 x sq rt 2)/2

To put it another way:

m=(sq rt 2)/2 x 13

n=(sq rt 2)/2 x 13

At a rock concert, the ratio of girls to boys is 3:7. If there are 360 more boys than girls, how many girls are at the concert?
bixtya [17]
You could understand the ration as parts: the total number of parts was 3+7=10.

So girls were 3/10 parts and boys 7/10 parts. The difference was 7-3=4 parts. this difference is equal to 360, so each part is 90 (4*90 =360).

so girls are "3 parts" and each part is 90, then the number of girls is 3*90=270.
