Answer:

Step-by-step explanation:

Y = x² - 2x + 5

x = -2

y = -2² -2(-2) + 5

y = 4 + 4 + 5 = 13

x = -1

y = -1² -2(-1) + 5

y = 1 + 2 + 5 = 8

x = 1

y = 1² -2(1) + 5

y = 1 - 2 + 5 = 4

x = 3

y = 3² -2(3) + 5

y = 9 - 6 + 5 = 8

x = 6

y = 6² -2(6) + 5

y = 36 - 12 + 5 = 29

$-2(a-8)+6a=36 \\ \\ -2a + 16 + 6a = 36 \\ \\ 4a + 16 = 36 \\ \\ 4a = 36 - 16 \\ \\ 4a = 20 \\ \\ a = \frac{20}{4} \\ \\ a = 5 \\ \\$

The final result is: a = 5.

Sandra saves 14% of her salary for retirement. This year her salary was $2,000 more than in the previous year, and she saved $7,

Brums [2.3K]

Answer: Sandra's salary in the previous year was $48,000

Step-by-step explanation:

Hi, the expression given is missing the $2000 more that she earns this year.

0.14 (x +2000) =7000

Where:

<em>x is Sandra's salary in the previous year. </em>
<em>0.14 is the decimal form of 14% (14/100=0.14) </em>

Solving for x :

0.14(x) +0.14 (2000) =7000

0.14x +280 =7000

0.14 x = 7000-280

0.14x = 6720

x = 6720/0.14

x=48,000

Sandra's salary in the previous year was $48,000

1/2 (6× + 18 ) = 1/3 (9x + 27)

joja [24]

The answer is No Solution because you get 3x + 9 = 3x + 9 which when you subtract 3x with 3x you would get No Solution.
