Answer: y=85
Step-by-step explanation: Substitute all x's in the equation with 8. y=2.5(8)+65. And solve y=85
The answer would probably be the last one cuz it’s true and it has more then one thing
The domain of the function is the complete set of possible values of the independent variable. (−∞,∞),{x|x ∈ R}
<h3>What is the domain function?</h3>
The domain is the set of values for which the given function is defined.
The given function;
f(x) = 2x + 5
The domain of the given function is all real numbers except where the function is undefined.
In this case, there is no real number that makes the function undefined.
The domain of the function is the complete set of possible values of the independent variable.
(−∞,∞),{x|x ∈ R}
The range is the set of all valid y values.

Answer:
= 403
Step-by-step explanation:
the sum to n terms of an arithmetic series is
= 
(a + l) ← a is the first term and l the last term
here a = - 5 and l = 67 , then
= 
(- 5 + 67) = 6.5 × 62 = 403
