Answer:

Step-by-step explanation:

No she is not correct because 2 times 3a is 6a and -2 times 2 is -4. And then 6a plus 4a is 10a. So therefore the equation would be 10a -4 which is not equivalent to 10a -2. Hope this helps you

No, she's not correct. The first expression is equal to 2 and the second expression is equal to 12. So, it's NOT CORRECT.

Select the expression in terms of n

Bumek [7]

Answer:

2n - 11

Step-by-step explanation:

Note there is a common difference d between consecutive terms of the sequence, that is

d = - 7 - (- 9) = - 5 - (- 7) = - 7 + 9 = - 5 + 7 = 2

This indicates the sequence is arithmetic with n th term

$a_{n}$ = a₁ + (n - 1)d

where a₁ is the first term and d the common difference

Here a₁ = - 9 and d = 2, thus

$a_{n}$ = - 9 + 2(n - 1) = - 9 + 2n - 2 = 2n - 11

-1/2x+2=-x+7 i need to know

ludmilkaskok [199]

$= \frac{ - 1}{ \: \: 2} x + 2 = x + 7$

$= \frac{ - 1}{ \: \: \: 2} x + 2 - x = 7$

$= \frac{ - 3}{ \: \: \: 2}x + 2 = 7$

$= \frac{ - 3}{ \: \ \: 2}x = 7 - 2$

$= \frac{ - 3}{ \: \: \: 2} x = 5$

$x = 5 \: \div \frac{ - 3}{ \: \: \: 2}$

$x = 5 \times \frac{ \: \: \: 2}{ - 3}$

$x = \frac{ - 10}{ \: \: \: 3}$

$∴ \frac{ - 1}{ \: \: \: 2} \times \frac{ - 10}{ \: \: \: 3} = \frac{ - 10}{ \: \: \: 3} + 7$
