Lee is thinking of two Numbers,the product is 18. the quotient is 2
defon
X, y - the numbers

The product is 18.
xy=18

The quotient is 2.
\frac{x}{y}=2 \ \ \ |\times y \\
x=2y

Substitute 2y for x in the 1st equation:
2y \times y=18 \\
2y^2=18 \ \ \ |\div 2 \\
y^2=9 \\
y=\pm \sqrt{9} \\
y=3 \ \lor \ y=-3 \\ \\
x=2y \\
x=2 \times 3 \ \lor \ x=2 \times (-3) \\
x=6 \ \lor \ x=-6 \\ \\
(x,y)=(6,3) \hbox{ or } (x,y)=(-6,-3)

The numbers are 6 and 3 or -6 and -3.

What are the coordinates of the vertices of the triangle under the translation (x y) (x − 1 y − 3)
Vsevolod [243]

Answer:

A: (-9,-3)(-2,-4)(-5,-8)

B: (-5,2)(-1,-3)(3,2)

C: (4,-7)(-1,-3)(4,1)

D: (-1,-11)(-2,-4)(-6,-7)

Step-by-step explanation:

So of the transformations, translations are pretty much the easiest.  x-1 just means move all coordinates left 1 and y-3 means move all coordinates down 3.  So for the first one the x coordinate gets 1 subtracted from it and the y value gets 3 subtracted from it.

(-8,0) => (-8-1, 0-3) = (-9,-3)

I do recommend double checking though, for practice and in case I flubbed a calculation.
