Q. Evaluate the expression for s=2.Write your answer in simplest form.−s+8−s+4=
Identify Expression: Identify the expression to be evaluated.We are given the expression (−s+4)/(−s+8) and we need to substitute s=2 into this expression.
Substitute s=2: Substitute s=2 into the expression.Substitute 2 for s in −s+8−s+4.Expression after substitution: −(2)+8−(2)+4
Simplify Expression: Simplify the expression.Simplify the numerator and the denominator separately.Numerator: −2+4=−2+4=2Denominator: −2+8=−2+8=6Now the expression looks like 62.
Reduce to Simplest Form: Reduce the fraction to simplest form.Both the numerator and the denominator are divisible by 2.62=(6÷22÷2)=31
