Identify which of the following equations represent functions. Select all that apply. A. y = 4x + 13 B. x = 5 C. x2 + y2 = 16 D. y2 = One-thirdx - 6 E. y = 3x2 - x - 1

The correct functions are y = 4x + 12 and y = 3x2 - x - 1  since y is dependent on x in both functions'

Function are expressions that consist of both an input value called the domain and the output value known as the range

For instance, y = mx + b is a function where x is the input value and "y" is the output value.

From the given options, the correct functions are y = 4x + 12 and y = 3x2 - x - 1  since y is dependent on x in both functions.

proofs involving isosceles triangles often require special consideration because an isosceles triangle has several distinct properties that do not apply to normal triangles.(more about triangle types) therefore, when you are trying to prove that two triangles are congruent, and one or both triangles, are isosceles you have a few theorems that you can use to make your life easier.

step-by-step explanation:

an isosceles triangle has two congruent sides and two congruent angles. the congruent angles are called the base angles and the other angle is known as the vertex angle. ∠bac and ∠bca are the base angles of the triangle picture on the left. the vertex angle is ∠abc
