Answer:
Step-by-step explanation:
Solve for x;
2x - ( x - 2 ) = 4x
distribute minus sign through parantheses
combine like terms
subtract x from both side
- x - x + 2 = 4x - x
- 2 = 3 x
Divide each side by 3
Answer:
Identity element property
Step-by-step explanation:
The property that justifies the step 3 is the identity element property.
Mathematically, the identity element is that number such that performing an arithmetic operation such as addition or multiplication with the number gives back the number we started with
For addition, the identity element is 0
while for multiplication, the identity element is 1
The answer is A or B but i think A is the true
Answer:
undefined
Step-by-step explanation:
x=-6 is a vertical line at x=-6.
Any vertical line has an undefined slope.
Let's pick two points on x=-6– (-6,1) and (-6,0)
(1-0)/(-6-(-6))=1/-6+6=1/0
Because you cannot divide by 0, a vetical line has an undefined slope.
