**Answer:**

The given equation which is in two variable is

⇒2 x + y =9

As we know that to get a unique solution you need two intersecting lines.

But here only one line is given.

On a single line there lie infinite number of points.

So, for different values of x we get different values of y or different values of y we get different values of x.

So , we can write the above equation as

either ⇒y=9-2 x Or x=9-2 y

I have drawn graph for you.

Thus , there are infinite number of solution of this equation. Like (0,9),(1,7),(2,5),(-2,13),(-1,11),(-3,15)......

<h2>1</h2>

**Step-by-step explanation:**

⅓ - (-⅔)

= 1/3 + 2/3

= 3/3

= 1

Lumber was only about 36.95% of the bid.

will be the answer.

**Step-by-step explanation:****-**

If the altitude to the hypotenuse of a right-angled triangle bisects the hypotenuse, then we can know that the triangle is **<u>Isosceles </u>****<u>right </u>****<u>t</u>****<u>r</u>****<u>iangle.</u>**** **(AB=AC)

Make AB=AC=2, so,

BC== =

Prime factorizing, we get,

BC =

Take two 2's outside by taking common because of "square" root,

⇢BC =

BD = DC = ,

AD = = =

So, AD=BD=CD= BC
