Find the vertex of the parabola with an equation y=-(-x-2)(x-4)
1 answer:
Answer:
(3,1)
Step-by-step explanation:
We can have the equation of the parabola re-written
the general form is;
y = a(x-h)^2 + k
where (-h,k) is the vertex
so we have
y = -1(x^2 -6x + 8)
y = -1(x^2 -6x + 9 - 1)
y = -1(x-3)^2 - 1)
y = -1(x-3)^2 + 1
So we have the vertex of the parabola as;
(3,1)

Step-by-step explanation:
Theres a lot!
First, simplify the equation 3X-8X is -5X. So 24=16+-5X. Then subtract 16 from both sides. So you get 8=-5X. Then divide by -5.
So X= -8/5
The answer is 31
29 - 13 is 16
16 + 15 is 31
