Which graph represents the inequality x≤2?
1 answer:
Answer:
Graph 2
Step-by-step explanation:
We are given the inequality x≤2
First off, with the inequality sign being ≤ rather than <, we know that 2 is also included. This means that x can be equal to 2 or less than 2.
Since 2 is included, we know we are looking for a solid line.
That said, we can eliminate the 1st and 4th graphs because there is a dotted line at 2, meaning that 2 is not included.
Next, based on the inequality sign, we know that values less than 2 satisfy it. So judging by the shaded region on each graph, we see that Graph 2 is the one that satisfies it.
For clarity's sake, one trick you can use is thinking of the inequality sign as an arrow. If it points left, values toward the left should be shaded and vice versa.
<u>Lastly, I'll give you the inequality for each graph.</u>
Graph 1: x<2
Graph 2: x≤2
Graph 3: x≥2
Graph 4: x>2

Answer:
<h2>A'(1,1), B'(2,3) and C'(2,1)</h2>Step-by-step explanation:
Notice that the vertices are A(1,1), B(2,3) and C(2,1).
A reflection across the x-axis give the coordinates A'(1,-1), B'(2,-3) and C'(2,-1). Then, we apply the rotation 90° clockwise about the origin A'(1,1), B'(3, 2) and C'(1, 2).
Finally, a reflection across the line y = x, gives A'(1,1), B'(2,3) and C'(2,1)
Therefore, the coordinates of the image are A'(1,1), B'(2,3) and C'(2,1).
