Answer:

Step-by-step explanation:

1. Lets Combine Like Terms. The only combineable terms are 8 and 8. So if we combine them they will equal 16. And we will have (2n+2)=16

2. Let's isolate the variable. We can do this by subtracting 2 from both sides. This will come out to 2n+14.

3. Let's further isolate the variable. We can do this by dividing both sides by two, which will finally come out to n=7

A fair die is rolled once. Let A be the event of rolling an even number, and let B be the event of rolling a number greater than

IRISSAK [1]

Answer:

A ∩ B = {4, 6}

Step-by-step explanation:

A die had 6 faces

S = {1, 2, 3, 4, 5, 6}

If A be the event of rolling an even number, then;

A = {2, 4, 6}

If B be the event of rolling a number greater than 3, then;

B = {4, 5, 6}

A ∩ B are the values that are common to both sets

A ∩ B = {4, 6}

Strike441 [17]

Answer:

x--------------y

4--------------2

8--------------3

12-------------4

Step-by-step explanation:

y = 1/4x + 1

We substitute the values under x into the equation

Equation 1: y = 1/4(4) + 1

Equation 2: y = 1/4(8) + 1

Equation 3: y = 1/4 (12) + 1

Let's solve for equation 1:

Equation 1: y = 1/4(4) + 1

y = 1/4(4) + 1

Multiply number in parenthesis

y = 1/4 * 4/1 + 1

1/4 and 4/1 turn into 1

y = 1 + 1

Add 1 to 1

y = 2

Let's solve for equation 2:

y = 1/4(8) + 1

Multiply number in parenthesis

y = 1/4 * 8/1 + 1

1/4 and 8/1 turn into 2

y = 2 + 1

Add 2 to 1

y = 3

Let's solve for equation 3:

y = 1/4 (12) + 1

Multiply number in parenthesis

y = 1/4 * 12/1 + 1

1/4 and 12/1 turn into 3

y = 3 + 1

Add 3 to 1

y = 4

So the table of values would be:

x--------------y

4--------------2

8--------------3

12-------------4
