Answer:

D) -3

Step-by-step explanation:

Slope of a linear function:

The slope of a linear function is the amount by which y changes when x increases by 1.

In this question:

When x = 1, y = 12

When x = 2, y = 9

When x = 3, y = 6

When x = 4, y = 3

So each time x increases by 1, y decreases by 3, which means that the slope is -3, and the answer is given by option D.

Can somebody help me with this question, please? I have no idea how to do this or find the answer. :/ How many ways are there to
san4es73 [151]

Answer:

28 different ways

Step-by-step explanation:

This is a combination question. Combination has to do with selection.

Total number of element in the set = 8

Number divisible by 6 or 8 are {-98, -48, -42, -36, -18, -6}

Total number divisible by 6 or 8 is 6

The number of ways we can choose 6 items from 8 is expressed as;

8C6 = 8!/(8-6)!6!

8C6 = 8!/(2)!6!

8C6 = 8*7*6!/2!6!

8C6 = 8*7/2

8C6 = 56/2

8C6 = 28 ways

Hence there are 28 different ways

Evaluate each expression if a = 6, b = 3, and c = 2.
earnstyle [38]

Answer:

a = 6, b = 3, and c = 2

1. ab1 = 6 × 3 × 1 = 18

2. c + 42 = 2 + 42 = 44

3. 18 = 18

4. a − b4  = 6 - 3(4) = 6 - 12 = - 6

5. 2c3 = 2 × 2 × 3 = 12

6. b ÷ 35 = 3÷35 = 0.086

7. a − 1 6 =  6 - 16 = -10

8. 6 + c8 = 6 + 2 (8) = 6 + 16 = 22

The table shows the results of a survey of students in two math classes.
qwelly [4]

P(more than 1 hour of TV | 6th period class) is  0.352.

<h3>What is the probability?</h3>

Probability determines the odds that a random event would happen. The odds of the random event happening lie between 0 and 1.

P(more than 1 hour of TV | 6th period class) = number of 6th period class students who watch tv for more than an hour / total number of students surveyed

12 / (12 + 9 + 5 + 8)

12 / 34 = 0.352
