Answer:
see explanation
Step-by-step explanation:
given the endpoints of a line segment
(x₁, y₁ ) and (x₂, y₂ ) then the midpoint is
[
(x₁ + x₂), (y₁ + y₂) ]
For example
consider the endpoints (4, 2) and (6, - 4)
midpoint = [(4 + 6), (2 - 4)] = (5, - 1)
Answer:
He is not correct because he made a sign error.
Step-by-step explanation:
-2 |8-x| - 6 = -12
-2 |8-x| = -12 + 6
-2 |8-x| = - 6
2 |8-x| = 6
|8-x| = 3
2 possible solutions:
8-x = 3 ----> x = 5
or
8-x = -3 ----> x = 11
Comparing the answer choices, we can see that Johan got the sign of x = 11 wrong.
Hence the correct answer is:
He is not correct because he made a sign error.
this is your expression
x / 1000 * -10
so x is the amount hiked so in this situation x = 3000
3000/1000 * -10
3 * -10
-30 degrees
the temperature wouldve dropped 30 degrees
