=12-5=7
=21-12=9
when u look at they have a diffrence of 2 so the answer will have a diffrence of 2 =11

Answer:
the diagonals bisect each other
Step-by-step explanation:
The midpoint formula tells you the midpoint M of segment XY is ...
M = (X + Y)/2
In your problem, the diagonals will bisect each other if they have the same midpoint. That is, we want to see if ...
(A +C)/2 = (B +D)/2
Multiplying by 2 can simplify our work a bit. In short, we want to test ...
A +C = B +D
(1, 4) +(-1, -4) = (4, -1) +(-4, 1) . . . . fill in the point coordinates
(1-1, 4-4) = (4-4, -1+1) . . . . . . . . . . simplify a bit
(0, 0) = (0, 0) . . . . . . . true, the midpoints are the same
The diagonals are mutual bisectors.
Answer:
The initial value is 1500
growth
43 % growth
Step-by-step explanation:
Exponential equations are in the form
y = a * b^x
a is the initial value
b is the growth or decay
b>1 is growth b-1 rate of growth
b <1 decay 1-b rate of decay
f(x) = 1500 * 1.43 ^x
The initial value is 1500
1.43 > 1 so it is growth
1- 1.43 = .43
Change to percent
43 % growth
X^2 - 2x - 8
2 numbers that multiplied give -8
2 numbers that added give -2
2 x -4 = -8
2 + -4 = -2
(x + 2) (x -4 )
roots equal = -2, 4
x^2 - 2x -8
a. b. c because b is -2 in the equation you don't plug b as a negative
in the axis of symmetry
axis of symmetry = -b divide by 2a
2 divide by 2(1) =1
Vertex= (1, -9)
