3x/x^ 2 - 6x = 1 . Solve for x.
Luda [366]

Answer:

Step-by-step explanation:

3x/x^ 2 - 6x = 1

3/x - 6x = 1

Multiply each term by x

3 - 6x² = x

6x² + x - 3 = 0

Using quadratic formula

X = [-b ± √(b² - 4ac)]/2a

a = 6, b = 1 and c = -3

X = [-1 ± √(1² - 4(6×-3)]/(2×6)

X = [-1 ± √(1 +72)]/12

X = [-1 ± √73]/12

X = [-1 ± 8.54]/12

X = (-1 + 8.54)/12 or (-1 - 8.54)/12

X = 7.54/12 or -9.54/12

X = 0.63 or - 0.8

At a concession stand, five hot dog(s) and two hamburger(s) cost $11.75; two hot dog(s) and five hamburger(s) cost $11.00. Find
serg [7]

Answer:

x:hot dogs

y: hamburger

5x + 2y = 11.75

2x + 5y = 11.00

10x + 4y = 23.50

-10x - 25y = -55.00

-21y = -31.50

y = $1.50 each hamburger

2x + 5(1.50)= 11.00

2x + 7.50 = 11.00

2x = $3.50

x = $1.75 each hot dog

What type of plate boundary joins mid ocean ridge segments quizzlet?
Anit [1.1K]
Mid ocean ridges are formed when two tectonic plates are drifting away from each other. This is known as a divergent or constructive plate boundary. Mid ocean ridges are formed as two oceanic plates move away from each other. The plates move as a result of convection cells in the mantle that generate convection currents. An example of a midocean ridge is the Mid Atlantic ridge where African plate drifts away from the north and south American plates.
