What is the vertex form of the equation y=-x^2 + 12x-4
please show all steps!
1 answer:
Answer:
y=-1(x-6)^2+32
Step-by-step explanation:
vertex form: y=a(x-h) ^2+k
you have your equation in standard form : ax^2+bx+c
how to change it:
vertex x=(-b)/2(a)
x=-(12)/2(-1)
x=6
substitute x into original (standard-form) equation to find y
vertex y=-(6)^2+12(6)-4
y=32
substitute those values into your vertex (h,k) : (6,32)
y=-1(x-6)^2+32
hope this helps!! :)

X + 4x = 40
5x = 40
5x/5 = 40/5
x = 8
1x 8 = 8
4x 8 = 32
Check=
8 + 32 = 40
The numbers are 8 and 32

It’s not a function
That’s all I know sorry!
The price was reduced by 34%, so she paid 100-34 = 66% of the original price.
16,000 x 0.66 = 10,560
She paid $10,560
