Answer:
e) SAS
f) Not enough information
Step-by-step explanation:
e) Sas because there is an angle in between two sides and for that angle is opposite angles
f) Not enough information because SSA is not a theorem
Answer:
The new center is the point (-x, y)
Step-by-step explanation:
When you reflect a point across the y-axis, the x-coordinate changes to its opposite (additive inverse).
See the attached image for an example.
The circle on the right has center (3, 1). When reflected across the y-axis, the reflected center is (-3, 1).

Step-by-step explanation:
Kindly check the attached image below for the full explanation.
Based on the preceding MBE values in the attached image below, the 3-Month moving averages appear better; however, exponential smoothing was penalized by including month 2 which was difficult for any method to forecast; using only the errors for months 0 to 12, the MBE for exponential smoothing is
MSE = 14694/9= 1632.72
exponential smoothing was better considering months 4 to 12.
Answer:
a = w - 3b + 4/6
Step-by-step explanation:
from the equation w=3(2a+b)-4 to make "a" the subject of the formulae
we have,
w = 6a + 3b - 4
by rearranging
6a = w-3b + 4
since we are making a the subject, we divide both sides by 6
we have
6a/6 = w - 3b + 4/6
therefore;
a = w - 3b + 4/6
