- 9x + 3y  - 27 = 0 \\ a =  - 9 \\ b = 3 \\ c = 0 \\  {b}^{2}  - 4ac = 9 - 4( - 9)( - 27) = 0 \\ x =  \frac{ - b}{2a}  =  \frac{  - 3}{ - 18}  =  \frac{1}{6}  \\ x =  \frac{1}{6}  \\ y = ( - 9 \times  \frac{1}{6} ) + 3y = 27 \\  \frac{ - 3}{2} + 3y = 27 \\ 3y = 27 +  \frac{3}{2 }  \\ 3y =  \frac{57}{2} \\ y =  \frac{57}{6}  =  \frac{19}{2}  \\

i hope it helps u.....

You’re supposed to graph the function. So basically you’ll want to make it so that y=, and then the rest of your formula.

So in this case y=3x+9

Consider the universal set U and the sets X, Y, Z. U={1,2,3,4,5,6} X={1,4,5} Y={1,2} Z={2,3,5} What is (Z⋃X′)⋂Y?
beks73 [17]

X' = U - X

= {1,2,3,4,5,6} - {1,4,5}

= {2,3,6}

(ZUX') = {2,3,5} U {2,3,6}

= {2,3,5,6}

(Z⋃X′)⋂Y = {2,3,5,6} ⋂ {1,2}

= {2}

The output is eleven more then the input
enot [183]
The input is known as x and the output is known as y in math.
So you’re stating that we’re making the equation equal the output, y, and we’re adding based off of the word “more”. Now that we know we’re adding, we have to find what we are adding together. We are adding x and 11 is that it equals y. Note that x and y could be many different variables and values.
Y= x+11
