Question 18
Algebraic ExpressionsIf y = x/(x − 3) + x/(x + 4) find y when x = −2
- A.−3/5
- B.3/5
- C.−7/5
- D.−2/5.
Show the answer and explanation
Answer: A (−3/5)
Explanation
y = −2/(−5) + (−2)/2 = 2/5 − 1 = −3/5.
If y = x/(x − 3) + x/(x + 4) find y when x = −2
Answer: A (−3/5)
y = −2/(−5) + (−2)/2 = 2/5 − 1 = −3/5.
