Answer:

  9/8

Step-by-step explanation:

The triangles are similar, so corresponding sides are proportional.

  AB/CB = AD/ED

  x/1 = (x+9)/9

  9x = x +9 . . . . . . multiply by 9

  8x = 9 . . . . . . . . .subtract x

  x = 9/8 . . . . . . . . divide by 8

On Friday,

I would make both denominators the same, and the lowest one that works is 18. So I'd make 1/9 into 2/18, and 1/6 into 3/18. They already used these times so combine them to make 5/18 then subtract that from the total time they had (18/18) and you would get 13/18 they spent playing music.

Which function in vertex form is equivalent to f(x) = 4 + x2 – 2x?
Alexus [3.1K]
<h3>Answer:</h3>

option A

f(x) = (x – 1)2 + 3

<h3>Step-by-step explanation:</h3>

Given in the question a function,

f(x) = 4 + x² – 2x

Step 1

f(x) = 4 + x² – 2x

here a = 1

        b = -2

        c = 4

Step 2

x = -b/2a

h = -(-2)/2(1)

h = 2/2

h = 1

Step 3

Find k

k = 4 + 1² – 2(1)

k = 3

Step 4

To convert a quadratic from y = ax² + bx + c form to vertex form,

y = a(x - h)²+ k

y = 1(x - 1)² + 3

y = (x - 1)² + 3
