Answer:
Solution is x=-3 and x =1, because that is zero od function y=-x^2-2x+3
Answer:
1. -2 = x
2. 19 = x
3. -22 = b
4. 30 = y
5. -5 = t
Step-by-step explanation:
1. -3x = 6 [-1 to the right side of the equivalence symbol]
2. 5x = 95 [23 to the right side of the equivalence symbol]
3. ᵇ/₂ = -11 [23 to the left side of the equivalence symbol]
4. ⅓y = 10 [7 to the right side of the equivalence symbol]
5. -2t = 10 [13 to the right side of the equivalence symbol]

To find the vertex, you need to find the axis of symmetry first.
In order to find the axis of symmetry we have to do -b/2a.
In our case, the b is -8 and the a is 1.
Plug it in.
-(-8)/2(1)
8/2 = 4
Our axis of symmetry is 4.
Now, we plug it into the equation to find the rest of the vertex.
y = 4^2 - 8(4) + 1
y = 16 - 32 + 1
y = -16 + 1
y = -15
Put it together.
Our vertex is (4,-15).
