3x-2 if x is less an or greater than 1, will be a negative y value.

-2x+3 when x is greater than 1 will also be a negative y value.

Answer:

The answer is the first plot.

Step-by-step explanation

The function changes its slope at x=1:

it is y=3x-2 when x<=1 so the slope is positive;

but it becomes y=-2x+3 when x>1 and the slope is negative.

The only plot that fits the description is the first one.

How many 4 digit numbers consisting of only the digits 2,4,6 and 8 are divisible by 4

Blababa [14]

Answer:

digits used once: 12
repeated digits: 128

Step-by-step explanation:

In order for a number to be divisible by 4, its last two digits must be divisible by 4. This will be the case if either of these conditions holds:

the ones digit is an even multiple of 2, and the tens digit is even
the ones digit is an odd multiple of 2, and the tens digit is odd.

We must count the ways these conditions can be met with the given digits.

Since we only have even numbers to work with, the ones digit must be an even multiple of 2: 4 or 8. (The tens digit cannot be odd.) The digits 4 and 8 comprise half of the available digits, so half of all possible numbers made from these digits will be divisible by 4.

<h3>digits used once</h3>

If the numbers must use each digit exactly once, there will be 4! = 24 of them. 24/2 = 12 of these 4-digit numbers will be divisible by 4.

<h3>repeated digits</h3>

Each of the four digits can have any of four values, so there will be 4^4 = 256 possible 4-digit numbers. Of these, 256/2 = 128 will be divisible by 4.
