Solve the rational equation 4/x=3x+2/x^2, and check for extraneous solutions.

Aleks [24]

Answer:

x = 2 is a solution

x = 0 is an extraneous solution

(Option 2)

Step-by-step explanation:

4/x = (3x + 2)/x²

4x² = 3x² + 2x

x² - 2x = 0

x(x - 2) = 0

x = 0, x = 2

Verification:

4/x = (3x + 2)/x²

At x = 2

4/2 = [3(2) + 2]/2²

2 = 8/4

2 = 2

At x = 0

4/0 = [3(0) + 2]/0²

Is undefined

Which are the coordinates of the midpoint of the segment connecting(15,-11) and (-10,10)

saveliy_v [14]

Answer:

Step-by-step explanation:

A(x1,y1) B(x2,y2)

M(x,y) => x= $\frac{x1+x2}{2}$ and y= $\frac{y1+y2}{2}$

-----------------------------------------------------------

A(15,-11) B(-10,10)

M( $\frac{15-10}{2}$ , $\frac{-11+10}{2}$ )=( $-\frac{5}{2}$ , $-\frac{1}{2}$ )
