Q. Is r=−8 r = -8 a solution to this equation?\newline−4=r2 -4 = \frac{r}{2} \newlineChoices:\newline(A)yes\newline(B)no
  1. Identify Equation: We have the equation:\newline−4=r2-4 = \frac{r}{2}\newlineIdentify the equation after substituting r=−8r = -8.\newlineSubstitute −8-8 for rr in −4=r2-4 = \frac{r}{2}.\newlineEquation: −4=−82-4 = \frac{-8}{2}
  2. Simplify Expression: Simplify (−8)/2(-8)/2.\newline(−8)/2=−4(-8)/2 = -4
  3. Check Solution: We found: −4=−4-4 = -4\newlineIs r=−8r = -8 a solution to the equation −4=r2-4 = \frac{r}{2}?\newlineFor r=−8r=-8, the equation becomes −4=−4-4 = -4, which is true.\newlineSo, r=−8r = -8 is a solution to the equation −4=r2-4 = \frac{r}{2}.
