Q. Which ordered pair is a solution of the equation?y+5=2(x+1)Choose 1 answer:(A) Only (5,10)(B) Only (−1,−5)(C) Both (5,10) and (−1,−5)(D) Neither
Understanding the equation: Understand the equation in question.The equation given is y+5=2(x+1). This is a linear equation in two variables, x and y.
Simplifying the equation: Simplify the equation.To find the solution, we need to simplify the equation to its standard form y=mx+b, where m is the slope and b is the y-intercept.y+5=2(x+1)y+5=2x+2y=2x+2−5y=2x−3
Testing the ordered pair (5,10): Test the ordered pair (5,10).Substitute x=5 and y=10 into the simplified equation to check if it satisfies the equation.10=2(5)−310=10−310=7The ordered pair (5,10) does not satisfy the equation.
Testing the ordered pair (−1,−5): Test the ordered pair (−1,−5).Substitute x=−1 and y=−5 into the simplified equation to check if it satisfies the equation.−5=2(−1)−3−5=−2−3−5=−5The ordered pair (−1,−5) satisfies the equation.
Determining the correct answer: Determine the correct answer based on the tests.Since the ordered pair (−1,−5) satisfies the equation and the ordered pair (5,10) does not, the correct answer is (B) Only (−1,−5).
