Answer:
Option D is the correct answer.
Step-by-step explanation:
Refer the given figure showing the graph.
We can see the point of intersection is (2.5, -2).
Option D is the correct answer.
<u>Alternatively:</u>
2x + y = 3 ---------------------eqn 1
2x - 5y = 15 ---------------------eqn 2
eqn1 - eqn 2 gives
2x + y - ( 2x - 5y) = 3 - 15
6y = -12
y = -2
Substituting in eqn 1
2x - 2 = 3
x = 2.5
Point of intersection is (2.5, -2).
Option D is the correct answer.

Answer: Vertex : Maximum (2, 0)
Rules:
- (x + d)² = x² + 2dx + d² and (x - d)² = x² - 2dx + d²
- x² + 2dx = (x + d)² - d² and x² - 2dx = (x - d)² - d²
Solve:
x² - 4x + 4
x² - 2(2x) + 2²
(x - 2)²
Into vertex form: a(x - h)² + k
1(x - 2)² + 0
Identify:
vertex : (h, k) = (2, 0)
Find additional things, to graph the equation:

Answer:
The correct option is 1.
Step-by-step explanation:
It is given than the area of the triangle ABC is 46cm².
Area of a triangle is
Base of the triangle is AB and height of the triangle is CD.
The area of the triangle is 46cm².
Therefore the length of side AB is 11.5 cm. Option 1 is correct.
