Which graph represents the inequality x≥2?
2 answers:
Answer:
The second graph in the upper line.
Step-by-step explanation:
We have been given an inequality . We are asked to find the graph of the given inequality.
Since our inequality has a greater than or equal to sign, so the boundary line of inequality would be solid line.
The boundary line would be vertical line passing through the x-axis at point .
Now, we will test point (0,0) to find the shaded area.
Since point (0,0) doesn't satisfy the given inequality, so shaded area of the given inequality would be area excluding point (0,0).
Therefore, option B is the correct choice.

Answer:
Step-by-step explanation:
Calculate the distance using the distance formula
d = √ (x₂ - x₁ )² + (y₂ - y₁ )²
with (x₁, y₁ ) = A(- 2, 5) and (x₂, y₂ ) = B(3, 8)
d =
