Answer:
x = 19
Step-by-step explanation:
These are vertical angles, which means that the angle measurements are going to be the same. Set the two angle measurements equal to each other:
3x - 3 = 6(x - 10)
Simplify. First, distribute 6 to all terms within the parenthesis:
3x - 3 = 6(x - 10)
3x - 3 = 6(x) - 6(10)
3x - 3 = 6x - 60
Isolate the variable, x. Note the equal sign, what you do to one side, you do to the other. Add 3 and subtract 6x from both sides:
3x (-6x) - 3 (+3) = 6x (-6x) - 60 (+3)
3x - 6x = -60 + 3
-3x = -57
Isolate the variable, x. Divide -3 from both sides:
(-3x)/-3 = (-57)/-3
x = -57/-3 = 57/3 = 19
x = 19 is your answer.

Line 1= undefined
Line 2= -4/3
Line 3= 4/3
Line 4= undefined
Line 5= 7/3
Line 6= -7/3
Line 7=no slope
Line 8=no slope
Line 9 =undefined
Line 10 = undefined
Line 11 = no slope
Line 12= undefined
NOTE: if the line is horizontal it have a zero slope or no slope and a vertical line the slope is undefined.
GCF - What is the highest number possible that the two given terms have in common.
In the given problem, one can clearly see that the two share

.
The factors of 14 are 1, 2, 7 and 14 while the factors of 42 are 1, 2, 3, 6, 7, 14, 21 and 42.
Out of the two, 14 is the highest number that they both share.
So our answer will be 14
Answer:

Step-by-step explanation:
Problems like this require that you recognize that the denominator of the right term is a factor of the denominator of the left term. That is, you're supposed to know how to recognize and factor the difference of two squares.
