How many solutions does the following equation have?

8x + 16 = 8x - 16

0

Step-by-step explanation:

If we add 16 to both sides, we get 8x+32=8x Then if we subtract 8x we get 32=0 which leads to nothing.

50-38=12

step-by-step explanation:

the solution of the equation is 2.23 ⇒ answer b

step-by-step explanation:

* lets revise the meaning of exponential function

- the form of the exponential function is y = ab^x, where a ≠ 0, b > 0 ,

b ≠ 1, and x is any real number

- it has a constant base b

- it has a variable exponent x

- to solve an exponential equation, take the log or ln of both sides,

and solve for the variable

* lets solve the problem

∵ [tex]7^{x}=77[/tex]

- the base is 7 and the exponent is x

- insert ㏑ in both sides

∴ [tex]ln(7^{x})=ln(77)[/tex]

- use the rule [tex]ln(a^{n})= nln(a)[/tex]

∴ x ㏑(7) = ㏑(77)

- to find x divide both sides by ㏑(7)

∴ [tex]x=\frac{ln(77)}{ln(7)}=2.23[/tex]

* the solution of the equation is 2.23 to the nearest 2 decimal places

None

Step-by-step explanation:

This equation has no solution because a non-zero constant never equals zero, therefore this equation is not true.
