Since this is an equilateral triangle, all 3 angles are equal, and all the sides are equal.
6x - 3 = 3x + 6
6x -3x = 6 +3
3x = 9
x = 3
we can check it by plugging 3 into each side for x: 6(3)-3 = 18-3 = 15
3(3)+6 = 9+6 = 15
5(3) = 15
So yes, the x = 3
I’m pretty sure there’s not supposed to be a second parenthesis after the - 6
Answer:
A
Step-by-step explanation:
Each domain value (x-value) of a function has exactly one range value (y-value).
A function can have two or more domain (x-value) having the same range (y-value)
Graph A shows the different domain value (x-values) having exactly one range value (y-value). No x-value has two different y-values.
Therefore, graph A is a function.

Answer:
a = - 1
b = - 9
c = 9
d = 3
e = 3
f = 2
g = 3/2
Step-by-step explanation:
For a;
6 - 2x = - (2x - 6)
For b;
-1 * 9 = - 9
For x ;
3x + (-9) = 3x - 9
3x - 9 = d(x - e)
Factorizing :
3(x - 3)
d = 3 ; e = 3
2x - 6 = f(x - 3)
Factorize :
2x - 6 = 2(x - 3)
3(x - 3) / 2(x - 3)
g = 3/2
