How do you work out the equation 1-x=9.
mafiozo [28]

Answer:

x=8

Step-by-step explanation:

x + 1 = 9

Simplifying

x + 1 = 9

Reorder the terms:

1 + x = 9

Solving

1 + x = 9

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-1' to each side of the equation.

1 + -1 + x = 9 + -1

Combine like terms: 1 + -1 = 0

0 + x = 9 + -1

x = 9 + -1

Combine like terms: 9 + -1 = 8

x = 8

Simplifying

x = 8

The incenter of a triangle is the center of its inscribed circle. <span>Generally, the easiest way to find the incenter is by first determining the </span>inradius and then<span> each side of the triangle can be </span>translated<span> by the length of the inradius, We also can use coordinate geometry through this formula:

</span>(\frac{ax_{1}+bx_{2}+cx_{3}}{a+b+c},\frac{ay_{1}+by_{2}+cy_{3}}{a+b+c})

Being a, b, c side lengths and with (x_{1}, y_{1}); (x_{2}, y_{2}); (x_{3}, y_{3}); the vertices.<span>
