Tyra solves the equation as shown.
- 3(x+2) = 9
1. - 3x - 6 = 9
2. - 3x = 15
3. x = - 5
the property tyra used in line 1 was the:
a) associative property
b) commutative property
c) distributive property
d) inverse property

We have been given the equation

The first steps is given as

In this step, Tyra has distributed the term -3 over the parenthesis, as shown below

We know the distributive property is given by

Therefore, we can say that Tyra has used distributive property in the first step.

C is the correct option.

the equivalent expression are always the hardest ones but you look at the gcf also

step-by-step explanation:

x coordinate can be written by using the formula, x= x1 + 2/5(x2 - x1)

step-by-step explanation:

formula

x = x1 + p/w(x2 - x1)

let the line segment ab with a(x1,y1) and b(x2,y2)

a point(x,y) divide ab in the ratio, 2: 3 the x coordinate can be written as

x = x1 + p/w(x2 - x1)

here p=2 and w = 2+3

therefore,

x coordinate can be written by using the formula, x= x1 + 2/5(x2 - x1)

similarly y coordinate y = y1 + 2/5(y2 - y1)
