Answer:

d)    \frac{13 - 5x}{2x -8}    

Step-by-step explanation:

<u><em>Explanation:-</em></u>

Given expression

                               \frac{\frac{3}{x-2}-5 }{2-\frac{4}{x-2}  }

we will do L.C.M  both numerator term and denominator term

                     ⇒    \frac{\frac{3-5(x-2)}{x-2} }{\frac{2(x-2)-4}{x-2}  }

on simplification , we get

                 

                ⇒    \frac{\frac{13-5x}{x-2} }{\frac{2x-8}{x-2}  }

cancellation 'x-2'

we will get

          \frac{13 - 5x}{2x -8}

Answer:

80 degrees

Step-by-step explanation:

We can use the Central Angle Theorum, which states that if the vertex of the angle is the center of the circle, then the arc is the same measurement as the angle.

In this case, m<COB is 80 degrees, and the vertex is the center of the circle, which means that measure of arc CB is also 80 degrees

Express each expression as a single logarithm.​
andreev551 [17]

Answer:

1. 6

2. 23

Step-by-step explanation:

1.

logx+1 ( x^2 + 2x + 1)^3

= 3logx+1  ( x^2 + 2x + 1)

= 3 logx+1 (x + 1)^2

= 6 logx+1 (x + 1)  Now the logx+1 x+1 = 1  so

The answer is 6.

2.

log11 11^23

= 23 log11  11

As in question 1 log11 11 = 1

So the answer is 23.

Idk what end behavior for this?
dangina [55]

Answer:

It is b.

Step-by-step explanation:

When x is negative x^5 will also be negative.

f(x) = x^5 - 3x^3 + 2x + 4

As x  --> -∞ x^5 will  be the main factor for f(x) --->  -∞ .

Similarly  x^5 will have the greatest influence when x ---> ∞, so f(x) ---> ∞.
