The required value of δ = 1/4.
0< |x-1| < δ
| f(x) - 4 | < 1/2 where f(x) = 6 - 2x
<h3>What are inequalities?</h3>
Inequality can be define as the relation of equation contains the symbol of ( ≤, ≥, <, >) instead of equal sign in an equation
now
| f(x) - 4 | < 1/2
|6 - 2x - 4 | <1/2
| 2-2x | < 1/2
| 1 - x | < 1/4
| x - 1 | < 1/4
since modulus function always give positive values.
0 < | x - 1 | < 1 /4
The required value of δ = 1/4.

Answer: the slope is -1/4. Hope this helps :)
Step-by-step explanation:
y=mx+b
m: slope
b: y-intercept
Answer:
B. 70
Step-by-step explanation:
We have the sum given by
Now, we open the summation by substituting the values of 'i',
i.e. = (1+11) + (2+11) + (3+11) +(4+11) +(5+11)
i.e. = 12 + 13 + 14 + 15 + 16
i.e. = 70.
Hence, the sum of is 70.
So, option B is correct.
