Answer:
(a) [8, 14]
(b) 
(c)See attachment
Step-by-step explanation:
We want to choose a value of x within 3 units of 11.
(a)Now, 11-3=8 and 11+3=14
The possible values of x ranges is in the closed interval [8,14]
(b) Since x is within 3 units of 11., we have:
Solving the absolute inequality
(c)To draw the number line, we use a closed dot since we have the less than or equal to sign.
Because the lines are parallel, 75 is equal to 11x-2
75=11x-2
77=11x
x=7
Answer:
Well Where are the graphs
Step-by-step explanation:
The inverse function theorem says
We have
defined on 
, for which we get
and
The derivative of 
is
So we end up with
To start we need to put all the b's on the same side.
4b + 6 = 2 - b + 4
To move the b on the right side to the left side, add b to both sides.
4b + 6 + b = 2 - b + 4 + b
Simplify. 4b + b = 5b and -b + b = 0 so...
The equation is now: 5b + 6 = 2 + 4
Now move 6 to the right side so we can isolate b.
5b + 6 - 6 = 2 + 4 - 6
Simplify.
5b = 0
Solve for b.
b = 0/5
b = 0
