Write a the equation of a line perpendicular to the line y=-7 and goes through the point (-2,3)
kap26 [50]

Answer:

y = 3x + 2

Step-by-step explanation:

Convert the equation to slope intercept form to get y = –1/3x + 2.  The old slope is –1/3 and the new slope is 3.  Perpendicular slopes must be opposite reciprocals of each other:  m1 * m2 = –1

With the new slope, use the slope intercept form and the point to calculate the intercept: y = mx + b or 5 = 3(1) + b, so b = 2

So y = 3x + 2

<span>  x^2 +(x-4)^2 =20^2</span>

<span>  x^2 +(x-4)^2 =400</span>

x^2 +(x-4)^2 -400=0

factor:

2x^2-8x-384=0

Factor the 2 out of 2X^2

2(x-16) (x+12) =0

<span> Divide both sides by 2</span>

(x-16) (x+12) =0

X=16 , x=-12

<span> Number cannot be negative so x=16</span>
