How do I solve this equation for x?
lara31 [8.8K]

Answer:

The answer is x = -32

Step-by-step explanation:

In order to find the value of x, e must first distribute the 6 into the parenthesis.

6(x - 7) = 8x + 22

6x - 42 = 8x + 22

Now we will add/subtract values so that all x values are on the right and all number values are on the left.

6x - 42 = 8x + 22

-42 = 2x + 22

-64 = 2x

Now to get the final answer, divide both sides by 2.

-32 = x

The radius of a circle is 4 feet. What is the area of a sector bounded by a 45° arc?
DIA [1.3K]

Answer:

Area = 6.28\  ft^2 or Area = 2  \pi\ ft^2

Step-by-step explanation:

Given

Radius, r = 4ft

Angle, \theta = 45

Required

Calculate the area of the sector

When angle is given in degrees, the area of sector is calculated as thus;

Area = \frac{\theta}{360} * \pi * r^2

Substitute\ r = 4\ and\ \theta = 45

Area = \frac{\theta}{360} * \pi * r^2 becomes

Area = \frac{45}{360} * \pi * 4^2

Area = \frac{45}{360} * \pi * 16

Area = \frac{45*16}{360} * \pi

Area = \frac{720}{360} * \pi

Area = 2 * \pi

Area = 2  \pi\ ft^2

The above is the area in terms of π

Solving further.... (Take π as 3.14)

Area = 2  \pi\ ft^2 becomes

Area = 2 * 3.14\  ft^2

Area = 6.28\  ft^2

Hence, the area of the sector is

Area = 6.28\  ft^2 or Area = 2  \pi\ ft^2

Why is it valid to say that both a function and its inverse describe the same relationship
liberstina [14]
A comparison between a function and its inverse would show that the domain and range of the original function swap. The domain of the function becomes the range of the inverse, the range of the function becomes the domain of its inverse. 

Looking at ordered pairs of the function and its inverse would look like this:

(2,4) on the original function becomes (4,2) on the inverse. 

While the graph of a function and its inverse are noticeably different an important thing to note is that it is merely a reflection across the line y=x. 

So even though they appear different you are looking at the same relationship just as y vs. x instead of x vs. y
