Answer:

There's only one solution x = 2

Thr solution x = 1 is an extraneous solution.

Step-by-step explanation:

\frac{1}{x - 1}  +  \frac{2}{x}  =  \frac{x}{x - 1}  \\  \frac{2}{x}  =  \frac{x}{x - 1}  -  \frac{1}{x - 1}  \\  \frac{2}{x}  =  \frac{x - 1}{x - 1}  \\  \frac{2}{x}  = 1 \\ 2 = x

vagabundo [1.1K]

Answer:

3x^{2} -2x +5=0

Step-by-step explanation:

Combine liked terms:

3x^{2}+5x+x-1x+6+2=7x+3

3x^{2}+6x-1x+8=7x+3

3x^{2}+5x+8=7x+3

Subtract 3: 3x^{2}+5x+8-3=7x+3-3

3x^{2}+5x+5=7x

Now subtract 7x:

3x^{2}+5x+5-7x=7x-7x

If you want combine liked terms:

3x^{2}-7x+5x+5=0

3x^{2}-2x+5=0

Hope this helps!

Use the properties of exponents to rewrite y=e^-0.75t in the form of a(1-r)^t
Ivahew [28]

Answer: y = (1 - 0.527)^t

Step-by-step explanation:

y=e^(-0.75t)


y=(e^-0.75)^t


y= 0.47236655^t


1 - 0.47236655 = 0.52763345

y = (1 - 0.527)^t
