Answer: 3 and -1/2.
Step-by-step explanation:
You can represent any linear inequality using any of the following forms:
When the sign is pointing towards x, it means that x is greater than b.
The line under the greater sign means that x can also equal b.
In your case, b is -4., as that is the point at which numbers are no longer part of the set. An open dot over -4 is a way to represent that -4 is not a part of the solution - so x cannot equal -4.
The options given:
So, your solutions are 3 and -1/2.
Answer:
The proved is given below.
Step-by-step explanation:
Given ABCD is a parallelogram and also ∠ABE equals 180°, ∠CBE ≅ ∠CEB
We have to prove that ∠DAE ≅ ∠CEA
As ∠CEA=∠CBE → (1)
and given ABCD is a parallelogram implies AD||CB
∴ ∠DAE=∠CBE → (2) as these are corresponding angles.
From equation (1) and (2), we get
∠DAE=∠CEA
Hence, ∠DAE is congruent to ∠CEA
Hence Proved
