Which inequality is represented by the graph? Which test point holds true for the inequality?

The graph represents the inequality_ . The test point_holds true for this inequality.

see the explanation

Step-by-step explanation:

From the graph take two points

we have

(-1,4) and (1,1)

Find the slope

The formula to calculate the slope between two points is equal to

substitute

Find the equation of the solid line in slope point form

we have

substitute

isolate the variable y

The solution of the inequality is the shaded area below the solid line

so

The equation of the inequality is

The solution is the shaded area below the solid line

All points belonging to the shaded area including the boundary line are part of the solution of the inequality

Example

point (0,2.5)

substitute in the inequality

----> is true

therefore

The point hold true for the inequality

a - base

b - exponent

so,

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
