Answer:
B = (-6, 6)
Step-by-step explanation:
If M is the midpoint of AB, then ...
B = 2M - A
B = 2(-1, 4) -(4, 2) = (-2-4, 8-2)
B = (-6, 6)
Answer:
280cm^2
Step-by-step explanation:
I am only looking for the shaded region which is 20 and 14 and 20*14=280
so my final answer will be 280cm^2
Answer: see attachment
<u>Step-by-step explanation:</u>
Since A = C = 105° and D = 60°,
then A + B + C + D = 360°
105° + B + 105° + 60° = 260°
B + 270° = 360°
B = 90°
Answer: The minimum reliability for the second stage be 0.979.
Step-by-step explanation:
Since we have given that
Probability for the overall rocket reliable for a successful mission = 97%
Probability for the first stage = 99%
We need to find the minimum reliability for the second stage :
So, it becomes:
P(overall reliability) = P(first stage ) × P(second stage)

Hence, the minimum reliability for the second stage be 0.979.
Answer:
Step 2 is wrong.
It should be 3x – <u>18</u> + 4x + 12 – 6x
Explanation:
3(x – 6) + (4x + 12) – 6x →
3x – 18 + 4x + 12 – 6x →
(3x + 4x – 6x) + (-18 + 12) →
x – 6
