Solve for x x + 4/x = -5

Mathematics
1 answer:
Arlecino [84]3 years ago
5 0

Answer:

x = -4 , x = -1

Explanation:

Multiply by x on both sides to get rid of fraction

x(x + 4/x) = x(-5)

x^2 + 4 = -5x

x^2 + 5x + 4 = 0

Factor

(x+4)(x+1) = 0

x = -4 , x = -1

Find the equation of the tangent to the circle x2 + y2 = 109 at point (-10,3)
konstantin123 [22]

Answer:

10x - 3y = -109 .

Step-by-step explanation:

x^2 + y^2 = 109

Implicit Differentiation:

2x + 2y.y' = 0

y' = -2x/2y = -x/y

So at the point (-10,3) the gradient of the tangent is -(-10)/3 = 10/3.

Equation of the tangent:

y - y1 = m(x - x1)

y - 3 = 10/3(x + 10)

y - 3 = 10/3 x + 100/3

3y - 9 = 10x + 100

-109 + 3y = 10x

10x - 3y = -109
