(x + 12)2 + (y+13)2 = 36 <br><br> What’s the steps to get the center and the radius?

Anon25 [30]

Step-by-step explanation:

${(x + 12)}^{2} + {(y + 13)}^{2} = 36 \\ {(x + 12)}^{2} + {(y + 13)}^{2} = {6}^{2} \\ equating \: it \: with \: \\ {(x - h)}^{2} + {(y - k)}^{2} = {r}^{2} \\ - h = 12 \implies \: h = - 12 \\ - k= 13 \implies \: k = - 13 \\ \therefore \: center \: = (h, \: \: k) = ( - 12, \: \: - 13) \\ \: \: \: \: {r}^{2} = {6}^{2} \implies \: radius \: (r)= 6 \: units$

Help this is really hars

We have to find the slope of the line that passes through this points:
p1(-2,15), p2(-8,-5)
the slope of a line through two points is calculated like this:
m = (y2 - y1)/(x2 - x1)
where x1,y1,x2,y2 are the coordinates of the two points, so we have:
m = (-5 - 15)/(-8 - (-2))
m = (-20)/(-8 + 2)
m = -20/-6
m = 10/3
that is the line slope

(Iv'e posted this question before, but I forgot the multiple choice answers)

<h3>Option D</h3><h3>The simplified version of 7x − 4(x − 8) = 56 is 3x + 32 = 56</h3>

<em><u>Solution:</u></em>

<em><u>Given expression is:</u></em>

$7x - 4(x - 8) = 56$

Use distributive property to simplify the expression

By distributive property,

a(b + c) = ab + ac

Therefore,

$7x - 4(x - 8) = 56\\\\7x - 4x + 32 = 56$

Combine the like terms : 7x - 4x = 3x

Therefore,

$3x + 32 = 56$

Thus option D is correct
