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.

A right triangle has legs of lengths 9 cm and 12 cm. calculate the length of the hypotenuse?

just olya [345]

Let the legs of the triangle be a and b, and the hypotenuse c.

Your first instinct might tell you to use the Pythagorean theorem to go about solving this because $c= \sqrt{a^{2}+b^{2}}$ . This works, but it is slow.

The fastest way to solve this is to recognize that the right triangle is a special triangle where the ratio of the sides are 3:4:5. This means that if the legs are 9 and 12, then the hypotenuse is 15 because 3*3 is 9, 3*4 is 12, and 3*5 is 15.

The median of the triangle is a segment that connects the vertex of the triangle to the midpoint of the side opposite to the vertex. <span>The altitude of the triangle is a segment that connects the vertex of the triangle to the side opposite to the triangle, which intersects that side at exactly 90°.</span>
