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: $y=-\frac{1}{2}x+1$

Write a situation that describes the inequality: 12x – 14 < 200

photoshop1234 [79]

For this case we must write a situation for the following inequality:

$12x-14$

Andres needs less than $200 to go on vacation. It is known that in his work he earns $12 per hour, he must also pay a debt of $14. We want to know how many days he gets less than $200. Assuming Andres works 8 hours a day.

x: Variable that represents the number of hours Andres works

$12x-14$
