What is the solution set of the equation?<br> <img src="https://tex.z-dn.net/?f=%5Csqrt%7Bx%7D%20-18%2B9x%3Dx" id="TexFormula1"

Answer:

x ∈ {2.07014981016}

Step-by-step explanation:

The equation can be rewritten as ...

√x = 18-8x

x = 324 -288x +64x²

64x² -289x +324 = 0

x = (289 ±√577)/128 ≈ {2.07015, 2.44548}

Since √x must be positive, we know that ...

18 -8x ≥ 0

x ≤ 18/8 = 2.25

The larger of the above solutions is extraneous, so the solution set is ...

x ∈ {(289 -√577)/128} ≈ {2.07015}

Answer:

x=24

Step-by-step explanation:

1/2x+2 = 1/2x^2+8

1/2x^2=1/4x

1/2x+2=1/4x+8

1/2x -1/4x =0.25x

0.25x+2=8

8-2=6

0.25x=6

0.25/6 = 24

x=24
