uhh help dont really understand the concept of these

Answers

Answer 1

Answer:

Step-by-step explanation:

hi i went over this in class today but we only did b and c.

so b is g^2x when simplified and c is x/f when simplified. Hope this helps :>

Answer 2

so the first one plug 5 in for x for both functions and then multiply the answers together.
the second one multiply the two functions together and then simplify it
the third one everytime you see an x make it a y and then make the f(x) into x and then solve for y so you basically undo everything from the one side to the other
the fourth one means the equation =8 so what value of x would make the equation =8

This table shows some college costs. How much more is tuition than the cost of fees and room and board? (table pic attached)

Answers

Answer:

7x +72

Step-by-step explanation:

Tuition - (room and board)

8x+75 - ( x+3)

Distribute the minus sign

8x+75 - x-3

7x +72

8x+3 = (x) =12 because if 8x + 75 means that x alone will still be 8 the x + 3 +5 =16

Conclusion: not arithmetic

Answer:

The sequence is not an arithmetic sequence.

Step-by-step explanation:

7 is getting added by 2 to get 9

9 is getting added by 2 to get 11

11 is getting added by 1 to get 12

As you can see, the sequence is not consistent. Therefore, it is not an arithmetic sequence.

Answers

Answer:

k > 24

Step-by-step explanation:

To solve an inequality you must isolate the variable. Do this by using the properties of equality, specifically the property of multiplication. To get k by itself multiply both sides by 4. This way k > 24. Then, you can check your answer by plugging in any number less than or equal to 24 and solving to see if it's true.

Answer:

k = 24

Step-by-step explanation:

k is greater than or equal to 24 and 4/4 = 1 so if k is greater than or equal to 24 than that could be 24/4 and that would equal 6. that is the answer to your question.
