What is the solution set for [-x]=10

X = -10

Because it is the "absolute value" of "10"

Here's why

-X - 10 = 0, right ?

So, now we have to add a positive 10 to each of our sides to get one step closer to our answer

-X + 10 = 0 ⬅️cancel this
0 + 10 = 10 ⬅️keep this

We can multiply by a negative 1 (-1 )

10(-1) = -10
0(-1) = -0

So that's how we found out that X = -10

Find the other endpoint of the line segment with the given endpoint and midpoint.

Shtirlitz [24]

Answer:

endpoint is (29, -13)

Step-by-step explanation:

Formula for midpoint is $(\frac{x_{1} + x_{2} }{2} ,\frac{y_{1} + y_{2} }{2} )$

So, let $(x_{2} , y_{2} )$ be the coordinates of the endpoint you are looking for.

$x_{1} = -9$ and $y_{1} = 7$

$(\frac{-9 + x_{2} }{2} , \frac{7 + y_{2} }{2} )$ = (10, -3)

$\frac{-9 + x_{2} }{2} = 10$ $\frac{7 + y_{2} }{2} = -3$

-9 + $x_{2}$ = 20 7 + $y_{2} = -6$

$x_{2} = 29$ $y_{2} = -13$

endpoint is (29, -13)

Answer:

sorry to answer late but..

Step-by-step explanation:

$\frac{1}{75} cm$ = $\frac{scale }{real}$

the wings of the real plane are 12 meters or 1200 cm

we want to solve for the scale, sooo do the algebra...get scale by it self..

real * $\frac{1}{75}$ = scale

1200 * $\frac{1}{75}$ = 16

The scale model wings are 16 cm 2.54 cm is one inch so the wings are approx. 6.3 inches
