y = −2x + 1
4x + 2y = −1
Replace Y in the second equation with the value of Y in the first one.
4x + 2(-2x +1) = -1
Distributive Property:
4x + -4x + 2 = -1
Combine like terms:
2 = -1 which is not true, so there are no solutions.
Answer:
x is equal to -21

Answer:
option C.
Step-by-step explanation:
The given graph is the bell shaped graph.
From the graph we can observe that the peak is at 69.
So, the mean of the data is = 69 .
Standard deviation is the deviation of the graph from the mean value.
= 72-69 = 3
Hence, the standard deviation is equal to 3.
So, the correct answer is option C.
Answer:
Step-by-step explanation:
<u>Measure of the inscribed angle is half the arc measure:</u>
- x = m∠ABC = 1/2mAC
- x = 1/2(82°) = 41°
