Answer:
B. y - 1 = -4[x - (-3)]
Step-by-step explanation:
Given:
Slope = -4
Point = (-3, 1)
Required:
Point-slope form of the line
Solution:
Equation of a line in Point-slope form is given as y - b = m(x - a).
Where,
a = -3
b = 1
m = -4
Plug in the values
y - 1 = -4[x - (-3)]
Answer:
Mean : 66
Mode: 80
Median:70
Step-by-step explanation:
Mean: sum divided by number of numbers. So, 330 divided by 5 which is 66
Mode most occurring, so 80.
Median arrange in ascending order and find middle value, so 70
Answer:
∠AEC = 139°
Step-by-step explanation:
Since EC bisects ∠BED then ∠BEC = ∠CED = 4x + 1
∠AED = ∠AEB + ∠BEC + ∠CED = 180 ← straight angle
Substitute values into the equation
11x - 12 + 4x + 1 + 4x + 1 = 180, that is
19x - 10 = 180 ( add 10 to both sides )
19x = 190 ( divide both sides by 19 )
x = 10
Hence
∠AEC = ∠AEB + ∠BEC = 11x - 12 + 4x + 1 = 15x - 11, hence
∠AEC = (15 × 10) - 11 = 150 - 11 = 139°
