What is the solution to the equation below? Round your answer to two

noname [10]

Answer:

D. x=5

The answer is x=4.50 then it is rounded off to 5. So, the answer is 5.

Step-by-step explanation:

Find the domain of the inequality: $2x-1\geq 0$

Rearrange terms to the left side of the equation: $2x\geq 1$

Divide both sides of the inequality by the coefficient of the variable:

=> $x\geq \frac{1}{2}$

The domain of the inequality is: $x\geq \frac{1}{2}$

Convert logarithm to exponential form: $2^{3}=2x-1$

Calculate the power: $8=2x-1$

Rearrange terms to the left side of the equation: $-2x= -8-1$

Calculate: $-2x=-9$

Divide both sides of the equation by the coefficient of the variable: $x=\frac{-9}{-2}$

=> $x=\frac{9}{2}$

=> $x=4.5\\$

Round the number: $x=4.50$

Answer: $x=4.50$

=> $x=5$

The points (8, -10) and (-21, 4) form a line segment.

Citrus2011 [14]

Answer:

The coordinates of the midpoint are;

(-6.5, -3)

Step-by-step explanation:

Here, we want to get the midpoint of the line segment

To get this, we use the midpoint formula;

(x,y) = (x1 + x2)/2, (y1 + y2)/2

Thus;

(x,y) = (8 - 21)/2, (-10 + 4)/2

(x,y) = -13/2 , -6/2

(x,y) = (-6.5 , -3)

Raffle tickets are being sold for a fundraiser. The function a(n) relates the

Vlada [557]

Answer:

If the function is

A(n) = 4n -25

and we wish to get the inverse function N(a)

We let

A(n) = a

n = N(a)

Plugging in the values

a = 4 N(a) - 25

Arranging the equation:

4 N(a) = a + 25

N(a) = (a + 25) /4

The answer is

N(a) = (a + 25) /4
