Answer: <u><em>A, because when x=1/-1 you don't need to write down the one meaning it is -x and then +2 is the y which means the full answer is y=-x+2</em></u>

Which sequence isn’t a geometric progression?
AVprozaik [17]

Answer: 3, 6, 9, 12

Step-by-step explanation:

A geometric progression has a common ratio.

2,6, 18 and 54 has a common ratio of 3. When you multiply the first number by 3, you get the second number and the same thing applies to the third number.

1, 5, 25 and 125 has a common ratio of 5. When you multiply the first number by 5, you get the second number and the same thing applies to the third number.

4, 8, 16 and 32 has a common ratio of 2. When you multiply the first number by 2, you get the second number and the same thing applies to the third number.

3, 6, 9 and 12 is an arithmetic progression as 3 is added to each number

Find the error and explain why its wrong
UNO [17]

Answer:

The last part.

Step-by-step explanation:

The error is only at the last part. Basically the answer part.

The answer should be —

13 \sqrt{5}

We don't multiply the square roots when adding or subtracting. That'd contradict the rules.

Here, we let the square root of five as x-term.

\sqrt{5}  = x

4 \sqrt{5}  + 9 \sqrt{5}  = 4x + 9x

As we add up, we would get 13x. Thrn we convert x-term back to square root of five.

The answer would be —

13x \\ x =  \sqrt{5}  \\ 13 \sqrt{5}

Remember that we don't multiply the square roots when adding or subtracting.
