It is possible for a system of equations to have no solution. We call this an inconsistent system. For a system of 2 equations and 2 unknowns, two parallel lines would be an inconsistent system. It is also possible for a system of 3 equations and 3 unknowns to have no solution. Describe a situation where this is occurs. It is not enough to post an example of an inconsistent system; you need to describe a situation in 3 dimensional space where this occurs. There is more than one answer and you may provide multiple answers. You may describe this in words or post a drawing.

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

∵

- the base is 7 and the exponent is x

- insert ㏑ in both sides

∴

- use the rule

∴ x ㏑(7) = ㏑(77)

- to find x divide both sides by ㏑(7)

∴

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