A circle has the equation x^2−8y−6x+y^2=4.
mylen [45]
Hello here is a solution :
x²-8y-6x+y²=4....(1)
A)
x²-6x = x²-2(3)x+9-9
         = x²-2(3)x+3²-9
x²-6x =(x-3)² -9
B)
y²-8y = y²-2(4)y +4²-16
y²-8y = (y-4)²-16
C)
in (1) :

(x-3)² -9 +(y-4)²-16 = 4
(x-3)² +(y-4)² = 29   ...<span>is the standard form of the equation

</span>   <span>Select answer 1 : 
</span><span>A: 3

   Reflection across x axis.

2). (x, y) → (-x, -y)

   Rotation of 180° about the origin.

3). (x, y) → (x - 4, y)

   Shifted 4 units left horizontally.

4). (x, y) → (x, y + 3)

   Shifted vertically up by 3 units

5). (x, y) → (x - 1, y + 4)

Can anyone help with this question pleasee
Vladimir [108]

Answer:

y = 1

Step-by-step explanation:

Given:

a^{3y - 5} = \frac{1}{a^2}

Apply the negative exponent rule

a^{3y - 5} = a^{-2}

The bases will cancel each other

3y - 5 = -2

3y - 5 + 5 = -2 + 5

3y = 3

\frac{3y}{3} = \frac{3}{3}

y = 1

A board game has 25 cards, each printed with a number from 1 through 25. Sameer shuffled the cards, and then selected 1 card.
Yuki888 [10]

Total number of cards = 25 .
Total number of possible draws = 25
Number of possible successes = 5

(The successful draws are 1, 2, 3, 9, and 18.)

Probability of success = 5/25  =  <em>1/5 </em> =  0.2  =  20%
