Answer:

27

Step-by-step explanation:

Using 3a-9 = 6 you can find the value of a:

3a-9=6

3a=15

a=5

Now you can substitute this value into 5a+2:

5(5)+2

25+2=27

Y is inversely proportional to x and y = 24 when x = 2.
bija089 [108]

Answer:

k = 48

For x = 6, y = 8.

Step-by-step explanation:

The general equation for inverse variation is

y = k/x

We are told that y = 24 when x = 2, so we plug in those two values in the general equation to find the value of k.

24 = k/2

k = 24 * 2 = 48

Now that we know k = 48, the equation for our case is

y = 48/x

Now we plug in x = 6 and find y.

y = 48/x

y = 48/6

y = 8

GalinKa [24]

Answer:

x = -1, -5

Step-by-step explanation:

{(x + 3)}^{2}  = 4 \\  =  >  {x}^{2}  + 2 \times x \times 3 +  {3}^{2}  = 4 \\  =  >  {x}^{2}  + 6x + 9 = 4 \\  =  >  {x}^{2}  + 6x = 4 - 9 \\  =  >  {x}^{2}  + 6x =  - 5 \\  =  >  {x}^{2}  + 6x  + 5 = 0 \\  =  >  {x}^{2}  + 5x + x + 5 = 0 \\  =  > x(x + 5) + 1(x + 5) = 0 \\  =  > (x + 1)(x + 5) \\  =  > x =  - 1 \:  \: or \:  \:  - 5
