Answer:

(-3.888, -2.547) and (1.131, -1.33)

Step-by-step explanation:

Graph: desmos.com/calculator/qknljhtr5n

y = x² + 3x − 6 is an upwards parabola with a vertex of (-1.5, -8.25) and x-intercepts (-4.372, 0) and (1.372, 0).

√(x + 6) − y = 4 is a square root function opening to the right, with a vertex of (-6, -4) and an x-intercept of (10, 0).

The two curves intersect at (-3.888, -2.547) and (1.131, -1.33).

Simplify<br> (3/2x+5) + (5/x-5)
tia_tia [17]

Answer:

(3x + 10) / (2x + 5)(x - 5).

Step-by-step explanation:

(3/2x+5) + (5/x-5)

= [3(x - 5) + 5(2x + 5) ] /  [ (2x + 5)(x - 5)]

= 3x - 15 + 10x + 25 /  (2x + 5)(x - 5)

= 13x + 10 / (2x + 5)(x - 5).
