Since x co-ordinates are constant, answer has to be difference in y co ordinates therefore the answer is 4

The distance between the two values is 4. -8 is 4 away from -12, and the value of x stays the same.

9. Felix has a bucket of golf balls. The table shows the number of golf balls of each color in the bucket. Felix selects a golf

mestny [16]

Answer:

The golf ball is 2 times a likely to be orange as it is to be pink

Step-by-step explanation:

A. green = 18, pink+white+orange = 23

18 not > 23

B. pink $\neq$ white $\neq$ orange $\neq$ green

C. pink x 2 = orange?

4 x 2 = 8

D. white x 7 = green?

white = 11

green = 18

11 x 7 = 77 $\neq$ 18

A certain circle can be represented by the following equation. x^2+y^2+18x+14y+105=0 What is the center of the circle? What is t

Gre4nikov [31]

Answer:

See below.

Step-by-step explanation:

Recall the equation for a circle:

$(x-h)^2+(y-k)^2=r^2$ , where (h,k) is the center and r is the radius.

We need to turn the given equation into the above format. We do this by completing the square.

First, group them:

$(x^2+18x)+(y^2+14y)=-105$

For the first section, complete the square for $x^2+18x$ :

$x^2+18x+81-81$

$(x+9)^2-81$

Do the same for the second:

$y^2+14y$

$y^2+14y+49-49$

$(y+7)^2-49$

All together:

$((x+9)^2-81)+((y+7)^2-49)=-105$

$(x+9)^2+(y+7)^2-130=-105$

$(x+9)^2+(y+7)^2=25$

The center is (-9,-7).

The radius is $\sqrt{25}=5$

At work, Elon takes a break 1/5 of each hour he works. He also takes a lunch break for 1/2 of an hour each day he works. Elo

Anton [14]

Answer:

$h=50\ hours$

Step-by-step explanation:

Let

h -----> the number of hours, Elon works during one 5-day work week

we know that

$12\frac{1}{2}\ h=\frac{12*2+1}{2}=\frac{25}{2}\ h$

Elon’s break time must be equal to 1/2 of an hour multiplied by 5 days plus 1/5 multiplied by the total hours h

$\frac{25}{2}=5(\frac{1}{2})+\frac{1}{5}h$

Solve for h

Multiply by 10 both sides to remove the fraction

$125=25+2h$

$2h=125-25$

$2h=100$

$h=50\ hours$
