Answer:
Step-by-step explanation:
For the limit of a function to exist, then the right hand limit of the function must be equal to its left hand limit as shown;
If the function is f(x), for f(x) to exist then;
Given the function;
Lets check if the above statement is true.
The right hand limit of the function occurs at x> 9
f(x) = 9-x
The left hand limit occurs at x<9
f(x) = x+9
From the above calculation, it can be seen that 
, this shows that the function given does not exist at the given point.
Answer:
Step-by-step explanation:
The second one because 3(2)=6 when you add 2 you get eight
Answer:
Step-by-step explanation:
Remark
By corresponding angles and vertical angles, these two angles are equal.
Equation
-1 + 14x = 12x + 17 Subtract 12x from both sides
Solution
-1 + 14x - 12x = 12x - 12x + 17
-1 + 2x = 17 Add 1 to both sides
-1+1 + 2x = 17 + 1
2x = 18 Divide by 2
2x/2 = 18/2
x = 9
Answer: y+8
Step-by-step explanation:
-2(y-1)+3(y+2)
-2y+2+3y+6
y+8
