5(6 + 2) = (5 • 6) + (5 • 2) would simplify to

30 + 10 = 30 + 10

30 + 10 is equal to 40

40 = 40, which means this is true

2(4 + 6) = (2 • 4) + (2 • 6) would be simplified to

8 + 12 = 8 + 12

8 + 12 is 20

20 = 20, which is true :)

If you apply the changes below to the absolute value parent function, f(x) = [xl,
Rus_ich [418]

Answer:

B:  g(x) = Ix - 4I + 6

Step-by-step explanation:

First, let's describe in a general way the transformations.

Vertical shift.

For a function f(x), a vertical shift of N units is written as:

g(x) = f(x) + N

If N is positive, the shift is upwards

If N is negative, the shift is downwards.

Horizontal shift.

For a function f(x), a horizontal shift of N units is written as:

g(x) = f(x + N)

If N is positive, the shift is to the left.

If N is negative, the shift is to the right.

Now we have the function:

f(x) = IxI

And we first have a shift of 4 units to the right, this is written as:

g(x) = f(x - 4)

Now we have a shift of 6 units up

This is written as:

g(x) = f(x - 4) + 6

Now, knowing that f(x) = IxI, we can write

g(x) = Ix - 4I + 6

Option B.

ivanzaharov [21]

Answer: c) 300 copies

Step-by-step explanation:

Let x represent the number of copies that you must sell to break even.

You decide to market your own custom computer software. You must invest 3,255 for computer hardware,and spend 2.90 to buy and package each disk. This means that the total cost of producing each software would be

3255 + 2.9x

If each program sells for $13.75, it means that the total revenue from selling each software would be

13.75x

In order to break even, total cost would be equal to total revenue. Therefore,

3255 + 2.9x = 13.75x

13.75x - 2.9x = 3255

10.85x = 3255

x = 3255/10.85

x = 300 copies
