Answer:
D. Y= -2x - 3
Step-by-step explanation:
The reason the answer is D is because it is the reverse form of standard. D shows that the form of slope-intercept for is y=mx + b.
Answer:
∠ B = 60°
Step-by-step explanation:
The exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.
(10x - 45)° is an exterior angle of the triangle , then
10x - 45 = 3x + 4x = 7x ( subtract 7x from both sides )
3x - 45 = 0 ( add 45 to both sides )
3x = 45 ( divide both sides by 3 )
x = 15
Then
∠ B = 4x = 4 × 15 = 60°
Answer:
Angle BAC corresponds with side length BC
Side length AC will correspond with angle ABC
Step-by-step explanation:
In a triangle, the side length will correspond to the angle opposite it and vice versa.
That is, the side length opposite angle A corresponds to the side of Angle A
Hence, in the triangle given above ;
Angle BAC corresponds with side length BC, because BC is opposite BAC
Side length AC will correspond with angle ABC, because AC is directly opposite angle ABC.
Answer:
the mean is 73.3 and the median is 77
Step-by-step explanation:
for mean you add up all the values and find the average for median you line them up in number order and find the number in the middle
