Answer:

(x+8)² + (y+13)² = 169

Step-by-step explanation:

Equation of circle:

(x-h)² + (y-k)² = r²

(h,k) is the centre, r is the radius

(x-(-8))² + (y-(-13))² = 13²

(x+8)² + (y+13)² = 169

Answer: the equation of the circle is

(x + 8)² + (y + 13)² = 169

Step-by-step explanation:

A circle is the set of all points in a plane equidistant from a fixed point called the origin or center.

The center of the circle is (-8, -13)

The formula for determining the equation of a circle us expressed as

(x - h)² + (y - k)² = r²

Where

r represents the radius of the circle

h and k represents the x and y coordinates of the center of the circle. Comparing with the given points,

h = - 8 and k = - 13

Radius, r = 13

Substituting into the formula, it becomes

(x - h)² + (y - k)² = r²

(x - - 8)² + (y - - 13)² = 13²

(x + 8)² + (y + 13)² = 169

The sum of three consecutive even integers is -78, what are the integers ?
Digiron [165]
First, you need to analize and understand the problem, then you must choose and strategy. There is a wide variety of strategies to solve a mathematical problem, in this case, you can use the following, which is based on the information given above:
 1. You have that t<span>he sum of three consecutive even integers is </span>-78<span>, therefore, you can given the variable </span>x&#10;<span> to the first integer, the second even integer is </span>x+2<span> and the third one is </span>x+4&#10;<span>.
 2. Calculate x:
 </span>x+(x+2)+(x+4)=-78<span>
 </span>3x+6=-78
<span> </span>x=-28&#10;<span>
 </span>x+2=-28+2=-26&#10;<span>
 </span>x+4=-28+4=-24&#10;<span>
 Therefore, the answer is:</span>-28,-26,-24&#10;

I need help with this equation please!<br><br> 15- w/4 = 28
Luda [366]

Answer:

w= -52

Step-by-step explanation:

We simplify the equation to the form, which is simple to understand  

15-w/4=28

Simplifying:

15-0.25w=28

We move all terms containing w to the left and all other terms to the right.  

-0.25w=+28-15

We simplify left and right side of the equation.  

-0.25w=+13

We divide both sides of the equation by -0.25 to get w.  

w= -52

Hope it Helps :) !!
