Answer:

y=-3

Step-by-step explanation:

Given Equation:  

                            9x +7y=-12\\             y=?       at    x= 1

Putting the given value of 'x' in the equation:

                            9(1) +7y=-12\\\\9+7y=-12\\\\7y=-12-9\\\\7y=-21\\\\y=-\frac{21}{7} \\y=-3

At x=1, the value of y is y=-3

Now.. on the first one \bf \sqrt{-27}\cdot \sqrt{-3}\impliedby \textit{first, you convert them to "i" form}
\\\\\\
\sqrt{3^2\cdot 3\cdot -1}\cdot \sqrt{3\cdot -1}\implies \sqrt{3^2}\cdot \sqrt{3}\cdot \sqrt{-1}\cdot \sqrt{3}\cdot \sqrt{-1}
\\\\\\
3\sqrt{3}\ i\cdot \sqrt{3}\ i\implies 3(\sqrt{3})^2\ i^2\implies 3\cdot 3\cdot i^2\impliedby recall\quad i^2=-1

Which of the following is a polynomial with roots 3,5i, and -5i​
Strike441 [17]

Answer:

f(x)=x^3-3x^2+25x-75

Step-by-step explanation:

Solve for x:

x^3 - 3 x^2 + 25 x - 75 = 0

The left hand side factors into a product with two terms:

(x - 3) (x^2 + 25) = 0

Split into two equations:

x - 3 = 0 or x^2 + 25 = 0

Add 3 to both sides:

x = 3 or x^2 + 25 = 0

Subtract 25 from both sides:

x = 3 or x^2 = -25

Take the square root of both sides:

Answer:  x = 3 or x = 5 i or x = -5 i
