12 × 4 = 48
15 × 2= 30
48 + 30 = 78
78 is the answer :)

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

1. A coal train in Montana starts from rest and accelerates at 2.5 m/s2 for 15s.

liq [111]

Answer:

Step-by-step explanation:

If a coal train in Montana starts from rest and accelerates at 2.5 m/s2 for 15s,let us calculate the final velocity of the train.

Use the equation of motion v = u + at where;

v is the final velocity

u is the initial velocity = 0m/s (starts from rest)

a is the acceleration = 2.5m/s²

t is the time = 15secs

Substituting the given parameters into the formula;

v = 0+(2.5)(15)

v = 0+37.5

v = 37.5m/s

Hence the final velocity of the train is 37.5m/s

X/4-5=-8 If anyone can answer id be very happy

svet-max [94.6K]

So first add 5 to both sides so you have x ÷ 4 = -3
Then multiply both sides by 4 to get x = -12
Hope this helps!
