solutions with two variables: is (2, 9) a solution to the inequality y > 2x + 4 9 > 2(2) + 4 so 9>8 is true is (-1, 2) a solution to the inequality y > 2x + 4 is (-1, 2) a solution to the inequality y ≥ 2x + 4 substituting for a variable evaluate y=x + 3 when x = 5. y=x + 3 y=5 + 3 y=8
Answer
Explanation:
Step1: Check (-1, 2) for $y>2x + 4$
Substitute $x=-1$ and $y = 2$ into $y>2x + 4$. We get $2>2(-1)+4$, which simplifies to $2> - 2 + 4$ or $2>2$. This is false.
Step2: Check (-1, 2) for $y\geq2x + 4$
Substitute $x=-1$ and $y = 2$ into $y\geq2x + 4$. We get $2\geq2(-1)+4$, which simplifies to $2\geq - 2 + 4$ or $2\geq2$. This is true.
Answer:
(-1, 2) is not a solution to $y>2x + 4$, but is a solution to $y\geq2x + 4$.
