Answer:

(-2,-3) and (2,-3).

Step-by-step explanation:

It is given that x ∈ {-2, 0, 2} and y ∈ {-3, -1, 0, 3} .

The given equation is

$y=1-x^2$

At x=-2,

$y=1-(-2)^2=1-4=-3\in y$

At x=0,

$y=1-(0)^2=1-0=1\notin y$

At x=2,

$y=1-(2)^2=1-4=-3\in y$

Therefore, the solution of given equation are (-2,-3) and (2,-3).

1- y= x/2 + 2
2- y= 3x +1
3- y= x/2 - 2
4- y= 3x - 1

Please answer this question

Free_Kalibri [48]

Answer:

Step-by-step explanation:

$log(3x^{3}) - log(x^{2}) = log(\frac{3x^{3}}{x^{2}})\\log(27) - log(x) = log(\frac{27}{x} )\\$

therefore,

$\frac{3x^{3} }{x^{2} } = \frac{27}{x} \\3x=\frac{27}{x} \\3x^{2} =27\\x= +3\\x=-3$

however, since logarithms cannot have negative arguments, x can only be +3

i.e. log(-3) is impossible, and will return MATH ERROR on a calculator.
