Which of the following equations has infinitely many real solutions? A. 4x + 1 = x - 1 B. 4x + 1 = 4x - 1 C. 4(x - 7) = 4x + 28 D. 4(x - 7) = 4x - 28

Answers

The equation that has infinitely many real solutions is:

B. 4x + 1 = 4x - 1

In this equation, when you simplify it, you'll find that it states 1 = 1, which is always true. This means there are infinitely many solutions because any value of x would make the equation true.

Which value of theta is not in the domain of validity for csc theta =1/sin theta

Answers

Answer with explanation:

The given expression is:

$\csc \Theta^(\circ) =(1)/(\sin \Theta^(\circ))$

Domain of Cosec theta,will be all values in Radian or degree except at the point where,

→sine(theta)≠ 0.

If theta is in either Degrees or in Radian, then

$\Theta\neq k \pi ,\text{Where k, is any Integer}$

The value of theta which is not in the domain for the validity of

$\csc \Theta^(\circ) =(1)/(\sin \Theta^(\circ))$

is, →→Theta(Ф)≠ k π, for any integer ,k.

Verify each identity give the domain of validity for each identity. It is very used to prove these identities for any value of theta in the domain. So I just specify the domain and leave verification for you to do t with standard values or on calculator. Because verification is an endless process. Proof is not. As proof seems to be simple I will do that which will amount to verification as well
