It’s the first one!! :)))
Answer:
B
Step-by-step explanation:
Given f(x) = 2x + 5 , that is a linear function.
This is defined for all real values of x
domain is x ∈ R
Answer:
The answer is 3x-27
Step-by-step explanation:
If the angles are vertical from each other it means they are congruent. 2x+30 is 63, you plug in the x, 2(30)+30. You do that to the second one and also get 63, 3(30)-27. Therefore 3x-21 is the answer.
