Answer:
C is correct.
Step-by-step explanation:
The angles in the triangle have to add up to 180 and 36+36+108 is 180.
Answer: X=-2 1/5, X=-1
Step-by-step explanation:
The distance from CF is 9 units, 1/5 that = 1 4/5, add that to -4 is -2 1/5.
The distance from BD is 6 units, 2/3 that =4, add that to -5 is -1.
Hope this helps!
Answer: x=5,-5
Explanation:
Take the root of both sides and solve.
Answer:
(- 2, 9 )
Step-by-step explanation:
Given a parabola in standard form, y = ax² + bx + c : a ≠ 0
Then the x- coordinate of the vertex is
= -
y = - x² - 4x + 5 ← is in standard form
with a = - 1 and b = - 4, thus
= - = - 2
Substitute x = - 2 into equation for corresponding y- coordinate
y = - (- 2)² - 4(- 2) + 5 = - 4 + 8 + 5 = 9
vertex = (- 2, 9 )
