Answer:

D;

(x + 1/2)^2 + (y- √57)^2 = 81

Step-by-step explanation:

Mathematically, the general equation of a circle is given as;

(x-a)^2 + (y-b)^2 = r^2

where (a,b) represents the circle center and r represents the radius of the circle

Thus, we have this as follows;

(a,b) = (-1/2, √57) , r = 9

Substituting these values;

(x + 1/2)^2 + (y- √57)^2 = 9^2

(x + 1/2)^2 + (y- √57)^2 = 81

Y=6 because if you break it down you get (11y+7) =73 then you subtract 7 from both sides to get 11y=66 then you divide 11 on both sides to get y=6

Amanda is having new tile installed in her kitchen. TileAll charges a flat fee of $378.00 plus $15.00 per tile. Kitchen Plus cha
myrzilka [38]

Answer:

C = 495 + 13.05x

60 tiles.

Step-by-step explanation:

$15.00 per tile plus a flat fee of $378.00 that charges Tile All.

Therefore, for x number of tiles, the total cost of installation will be  

C = 378 + 15x ........... (1)

Again, $14.50 per tiles plus a flat fee of $550.00 that charges Kitchen Plus. Amanda has at Kitchen Plus, a 10% discount coupon.

Therefore, for x tiles installation the charges will be  

C = (550 + 14.5x)(1 - \frac{10}{100}) = 495 + 13.05x .......... (2) (Answer)

Now, if for x number of tiles both the company charges the same, then  

378 + 15x = 495 + 13.05x (From equations (1) and (2)}

⇒ 1.95x = 117

⇒ x = 60 tiles. (Answer)

Rewrite the following quadratic functions in intercept or factored form. Show your work.
Mariulka [41]

<u>Answer:</u>

y = 5x (x+2)

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

We are given the following the quadratic function and we are to rewrite it in intercept or factored form:

y = 5x^2 + 10x

We can factorize the given expression so taking the common factors out of it to get:

y=5x^2 + 10x

y = 5x (x + 2)

Therefore, the factored form of the given quadratic function is y = 5x (x+2).
