Answer:

(x-3)^2=2

Step-by-step explanation:

${x}^{2} - 6x + 7 = 0 \\ adding \: 2 \: both \: sides \\ {x}^{2} - 6x + 7 + 2 = 0 + 2 \\ {x}^{2} - 6x + 9 = 2 \\ {x}^{2} - 6x + {(3)}^{2} = 2 \\ (x - 3) ^{2} = 2$

What is the area of shaded section of the circle?

bazaltina [42]

Answer:

≈ 565.5 units²

Step-by-step explanation:

The area (A) of the shaded sector = area of circle × fraction of circle

A = πr² × $\frac{162}{360}$ ← r is the radius

= π × 20² × $\frac{162}{360}$

= 400π × 0.45 ≈ 565.5 units²

The operation * on the set Z of integers is defined by x*y = 3x + 2y - 1, x, y E Z. Find the value of x such that x*2=5

Assoli18 [71]

Answer:

x = 2/3

Step-by-step explanation:

Let's unpack the equation $x*2=5$ from our definition of $*$ :

$x*2=3x+2(2)-1=5$ (where $x\in \mathbb{Z}$ )

Now that we've got things defined in terms of familiar operations, we can simplify and solve for x:

$3x+2(2)-1=5\\3x+4-1=5\\3x+3=5\\3x=2\\x=2/3$
