Answer:
y-27=8·(x-3)
Step-by-step explanation:
y= -4x² - 16x - 14
Take the coefficient of x² as the common factor
y = - 4(x² + 4x + 7/2)
Add (b/2)² to complete the square
y = - 4( x² + 4x + 2² - 2² + 7/2)
Complete the square
y = -4( (x + 2)² - 1/2)
Remove the bracket
y = -4(x + 2)² + 2
Answer: y = -4(x + 2)² + 2
When simplified, the answer is 1
Answer:
∠CED = 48°
Step-by-step explanation:
By adding all angles together, they’ll eventually equal ∠AED. Hence, sum of all given angles = ∠AED
∠AEB + ∠BEC + ∠CED = ∠AED
29°+12°+x = 89°
Solve for x and we will get measure of ∠CED:
41°+x = 89°
x = 89°-41°
x = 48°
Therefore, the measure of ∠CED is 48°
