Answer: 4
Step-by-step explanation:
Using pythagoras theorem =>
b=
b=
b=
b=
b=4
12-x(5-4k)=y
12-y=x(5-4k)
12-y/(5-4k)=x
Y = x^2 -3
y = (x-3)(x+3)
For x-intercepts, y = 0
Therefore (x-3)(x+3) = 0
x intercepts are (3,0) and (-3,0)
The line of symmetry is x = 3+(-3) = 0
Vertex is on the line of symmetry
When x = 0, y = -1
Vertex = (0,-1)
The multiplicative inverse of -1/3 is -3.
The product of a number and it’s multiplicative inverse equals 1.
So... -1/3 x -3/1 = 1
A negative times a negative equals a positive.
I hope this helped!
