Find the value of x for which m is parallel to n <br> A) 10<br> B) 12<br> C) 40<br> D) 52
Klio2033 [76]

Answer:  x=5\textdegree

Explanation:

Since we have given that

line m and line n are parallel to each other,

So,

Corresponding angles are equal , as shown in the figure ,

According to question,

19x\textdegree=180\textdegree-17x\textdegree\\\\19x\textdegree+17x\textdegree=180\\\\36x\textdegree=180\textdegree\\\\x=\frac{180}{36}\\\\x=5\textdegree

Hence, x=5\textdegree

Answer:

<em>Domain ⇒ All Real Numbers, Range ⇒ y < 0; Option D</em>

Step-by-step explanation:

Take a look at the procedure below;

First simplify f ( x ) = - 4 * ( 8 )^x, such that it is ⇒

f ( x ) = - 2^2 * 8^x,

f ( x ) = - 2^2 * ( 2^3 )^x,

f ( x ) = - 2^2 * 2^3x,

f ( x ) = - 2^2 + 3x,

Now if we take a look at the domain we can see that it has no undefined points nor domain constraints, thus;

- ∞ < x < ∞

However, the range of the function is present in the form - c * n^ax + b, where f ( x ) < k, and k = 0;

f ( k ) < 0, y < 0

<em>Solution; Domain ⇒ All Real Numbers, Range ⇒ y < 0; Option D</em>
