Answer:
none of the choices
Step-by-step explanation:
f(x) = 3-x
Let x=-1
f(-1) = 3 - (-1)
= 3+1
=4
f(-1) =4
Answer: An equation may have more than one solution, or the solution(s) may be complex, rather than real, but it will always have one solution - and sometimes more than one.
Step-by-step explanation:
Answer:
x=8
Step-by-step explanation:
Those angles are supplementary so:
140+5x=180
5x=40
x=8
1. Similar: all angles are equivalent.
2. Similar: 2 angles and 1 side are equivalent.
