Q. Find limx1x11x+7 \lim _{x \rightarrow 1} \frac{x-11}{x+7} .\newlineChoose 11 answer:\newline(A) 2-2\newline(B) 54 -\frac{5}{4} \newline(C) 32 \frac{3}{2} \newline(D) The limit doesn't exist
  1. Substitution of xx: To find the limit as xx approaches 11, we can directly substitute xx with 11 in the expression (x11)/(x+7)(x-11)/(x+7), since the denominator does not become zero and there is no indeterminate form.
  2. Arithmetic calculation: Substitute x=1x = 1 into the expression: limx1x11x+7=1111+7\lim_{x \to 1}\frac{x-11}{x+7} = \frac{1-11}{1+7}
  3. Fraction simplification: Perform the arithmetic: (111)/(1+7)=(10)/8(1-11)/(1+7) = (-10)/8
  4. Final answer: Simplify the fraction: (10)/8=5/4(-10)/8 = -5/4
  5. Final answer: Simplify the fraction: (10)/8=5/4(-10)/8 = -5/4 The simplified fraction 5/4-5/4 corresponds to answer choice (B).
