Answer:
the rational numbers that doesn’t have a reciprocal are [math]0 [/math] (which can also be expressed as [math]\frac {0} {x}, x \neq 0 [/math] ), and any number of the form [math]\frac {x} {0} [/math].
Step-by-step explanation:
The result of the evaluation of the equation given in the task content is; x =-2.
<h3>What is the solution of the equation?</h3>
It follows from the task content that the equation given whose solution is to be determined is;
3[-x + (2 x +1)]=x-1
The equation can be solved as follows;
-3x + 6x +3 = x-1
2x = -4
x = -2

Only three terms luckily:
8*(1/4)^0 + 8*(1/4)^1 + 8*(1/4)^2 =
8*(1 + 1/4 + 1/16) = 21/2, answer D.
