Answer:

C. symmetric with respect to the origin

Step-by-step explanation:

A graph must pass the vertical line test to be called the graph of a function. No function will ever be symmetrical with respect to the x-axis, because that would mean it fails the vertical line test.

An even function is symmetrical about the y-axis. An even function has the characteristic that ...

f(-x) = f(x) . . . . an even function

An odd function is symmetrical about the origin. An odd function has the characteristic that ...

f(-x) = -f(x)

The given function is f(x) = -1/x. Then the value of f(-x) is ...

f(-x) = -1/-x = 1/x = -f(x)

The given function is an odd function, so is symmetrical about the origin.

Answer:

1) 3/4

2)7/8

3)5/6

Step-by-step explanation:

$\frac{1}{2} \times 2 = \frac{2}{4}$

2/4+1/4=3/4

$\frac{1}{2} \times 4 = \frac{4}{8}$

4/8+3/8=7/8

$\frac{1}{2} \times 3 = \frac{3}{6}$

$\frac{1}{3} \times 2 = \frac{2}{6}$

2/6+3/6=5/6

You have $47 to spend on music and movie downloads Each album download costs $7 and each movie download costs $8. Write and grap

mel-nik [20]

Answer:each album costs $7 and you buy x of them

cost of albums = 7x

each movie costs $8 and you have you have y of them

cost of movies = 8y

total cost is has to be less than $47

---> 7x + 8y < 47

sketch the graph of 7x + 8y = 47 , a straight line, and shade in the region below that line. Of course you would stay in the first quadrant, (x > 0, and y >0 , since you can't have negative number of movies and albums)

Since you can't buy partial albums and movies, both x and y have to be whole numbers.

So for solutions you would consider only ordered pairs that have whole numbers as their components.

e.g. (2, 2) or (1,5)

Step-by-step explanation: Hope this helps :)
