A fraction equivalent to 3/12 can be 1/4. You can multiply a same number on both numerator and denominator to get other fractions.

Answer:

y = \frac{6}{5}

Step-by-step explanation:

Given

6 | 5y - 1 | - 1 = 29 ( add 1 to both sides )

6 | 5y - 1 | = 30 ( divide both sides by 6 )

| 5y - 1 | = 5

The absolute value function always returns a positive value. However, the expression inside can be positive or negative, thus

5y - 1 = 5 ( add 1 to both sides )

5y = 6 ( divide both sides by 5 )

y = \frac{6}{5}

OR

- (5y - 1) = 5, that is

- 5y + 5 = 5 ( subtract 5 from both sides )

5y = 0 ⇒ y = 0

As a check substitute these values into the left side and if equal to the right side then they are the solutions.

x = 0 : 6|0 - 1 | - 1 = 6 | - 1| - 1 = 6(1) - 1 = 6 - 1 = 5 ≠ 29

x = \frac{6}{5} : 6 | 6 - 1 | - 1 = 6(5) - 1 = 30 - 1 = 29

Thus x = \frac{6}{5} is a solution, x = 0 is extraneous

II. Let f(x) = 9 – x , g(x) = x2 + x, and h(x) = x – 2. Compute the following:
Neko [114]

Answer:

h(g(x))=x^2+x-2

h(g(f(x))= x^2-19x+88

Step-by-step explanation:

<u>Composite Function</u>

Suppose f(x) and g(x) are real functions, the composite function named (f\circ g)(x) is defined as:

(f\circ g)(x)=f(g(x))

The composite function can be found by substituting g into f.

We are given these functions:

f(x)=9-x

g(x)=x^2+x

h(x)=x-2

Find:

a) h(g(x))

Substituting g into h:

h(g(x))=x^2+x-2

b) h(g(f(x))

First we find g(f(x)):

g(f(x))=(9-x)^2+(9-x)

Operating:

g(f(x))=81-18x+x^2+9-x

Simplifying:

g(f(x))=90-19x+x^2

Now find h(g(f(x)) replacing the above equation into h:

h(g(f(x))= 90-19x+x^2-2

Simplifying and rearranging:

h(g(f(x))= 88-19x+x^2

h(g(f(x))= x^2-19x+88

About 650,000 people live in a circular region with a 6-mile radius. Find the population density in people per square mile.
Lunna [17]
To find the population density we need to divide population by area then live on:
density= \frac{population}{area}

The given number live in a circular place. Area is given by formula:
A= r^{2}  \pi
Where r is radius

Now we have:
density= \frac{650000}{ 6^{2}  \pi } =\frac{650000}{ 36  \pi }=5747.26

The population density is 5747.26 people per square mile.
