Answer:

Distributive property says that:

a\cdot(b+c) = a\cdot b + a\cdot c

Addition property of equality:

if x = y then x+z = y+z

Division property of equality:

if x = y then \frac{x}{z}=\frac{y}{z}

As per the statement:

Given the equation: -3(x+2)=9

Tyra solve this equation as shown below:

1.

-3x -6 = 9               [Distributive property]

2.

-3x = 15                 [Addition property of equality]

3.

x = -5                    {Division property of equality]

Therefore, the  property Tyra used in line 1 was : Distributive Property.

Answer: In line 1 distributive property is used


Step-by-step explanation:

Given equation :

-3(x+2)=9

Tyra solves it as :

1. -3x-6=9

2. -3x=15

3. x=-5

In 1. Distributive property is used i.e.

a.(b+c)=a.b+a.c

2. Addition property is used

i.e.If a=b then a+c=b+c

3. Division property is used

i.e. If a=b then

\frac{a}{c}=\frac{b}{c}

Therefore the property used in line 1 is :

Distributive property

ABC is formed by two tangents intersecting outside of a circle. If minor arc AC = 98°, what is the measure of ∠ABC?
gregori [183]
It's 82 degrees. Subtract your minor arc (98) by 360 to get your major arc, which is 262. Then, subtract 98 (minor arc) from 262 (major arc), which gives you 164. Finally, divide 164 by 2 to get angle ABC.
