Answer: The number 0
x^2 + 8x - 4 = x^2 + 8
8x - 4 = 8 ... subtract x^2 from both sides
8x = 12 .... add 4 to both sides
x = 12/8 .... divide both sides by 8
x = 3/2 ... reduce
x = 1.5 .... convert to decimal form
Now plug x = 1.5 into the expression 2x-3 and simplify
2x-3 = 2*1.5-3 = 3-3 = 0 which is the answer
Hey there!
(0.4 + 1.6) × 6
= 2 × 6
≈ 2 + 2 + 2 + 2 + 2 + 2
≈ 4 + 4 + 4
≈ 8 + 4
≈ 12
Therefore, your answer is: 12
Good luck on your assignment & enjoy your day!

Answer:
Havent learned it yet
Step-by-step explanation:
sorry my bad how do i
4 5 8 11
5+8/2 = 6.5
Hope this helps!
Step-by-step explanation:
The basic form of equation:
(x-h)²=4a(y-k),
(h,k)=coordinates of vertex
(h, k+a) = coordinate of focus
For given parabola:
axis of symmetry: x=2
(h, k) =(2,-3)
(h, k+a)=(2,5)
k+a=5
-3+a=5
a=8(distance from vertex to focus on the axis of symmetry)
equation: (x-2)²=4×8(y+3)
(x-2)²= 32(y+3)
