Y varies inversely with x, if y = -12 when x = 8 what is x when y = -9
Minchanka [31]

Answer:

either 5 or 11

Step-by-step explanation:

(8, -12)

(5, -9) or (11, -9)

If y varies consistently with x then it would copy what happens, in a manner of speaking.

In this case, y increases by three, x would either add 3 or subtract 3

I am not completely sure on this.

A is the correct answer
(to find diagonal of a square , you can get help from Pythagorean Theorem)

{10}^{2}  + 10 {}^{2}  =  {x}^{2}  \\ 100 + 100 =  {x}^{2}  \\  {x}^{2}  = 200 \\ x =  \sqrt{200}

How do i solve this equation?
FrozenT [24]
If you took both sides to be powers of 12, you would get

12^log(5) =5 = -3k+7= 12^log(-3k+7)

can you do
5=-3k+7?
