Answer:
x = 3
Step-by-step explanation:
Set up as proportion and cross multiply to solve:
3/4 = 2.25/x
x = 3
We can usually get a couple of facts for these that let us rule out answers without working out all the details.
The green and red areas are below a CUP parabola, opening up. CUP stands for concave up positive, and tells us there's a positive coefficient on x². Unfortunately all the choices have a positive 1 coefficient, no help here.
Since the areas are below they're going to be y ≤ x² + other stuff. That rules out B and C.
The red and blue parts are below the line, and the line has a positive slope. So that's y ≤ mx + b where m>0 is the positive slope. That rules out D with the negative slope.
Answer: A
Answer: (2, 3)
Step-by-step explanation: This graph depicts a parabola. The vertex of a parabola is the point at the intersection of the parabola, and it is the line of symmetry. In other words, it is the point where the parabola crosses its axis of symmetry. Therefore, the ordered pair of (2, 3) represents the vertex of this graph.
