Answer:
AB ≈ 4.41
Step-by-step explanation:
Using the cosine ratio in the right triangle
cos25° =
=
=
( multiply both sides by AB )
AB × cos25° = 4 ( divide both sides by cos25° )
AB =
≈ 4.41 ( to the nearest hundredth )
Answer:
one solution
Answer: The given equation 3x − 7 = 4 + 6 + 4x has one solution.J
Step-by-step explanation:
To reflect a function across the x axis, we want to turn all the x values that were once positive negative and vice versa. That means we want f(-x), which is: 
Answer:
It means if y is one then x is one and if x is 6 then y is 6.
