Answer:
Vertex is (-4,3)
Step-by-step explanation:
rewrite the problem from y=-2(x+4)^2+3 to y=ax^2+bx+c
y=-2x^2-16x-29
the parabola points are: a=-2 b=-16 c=-29
then divide x= -b/2(a)
x= -(-16)/2(-2)
simplify: x=-4
go back and plug in x=-4 to get y
y=3
Answer is (-4,3)
Answer:
18 units
Step-by-step explanation:
This is because 3+6+3+6=18.
Answer:
D
Step-by-step explanation:
Short Answer; it pretty much has to be Isosceles.
Let the smallest angle (represented by 1) be x
Then the other two angles are 2x and 2x
Every triangle has 180o and 3 angles.
x + 2x + 2x = 180
5x = 180 Divide by 5
x = 180/5
x = 36
Therefore the angles are
36
72
72
Two angles are the same. The triangle is Isosceles.
A: f(x) = 3x - 1
B: f(x) = -x + 3
C: f(x) = 3
D: f(x) = x+3
