D - -x^2 + 3x + 7
To find this, first write out the equation:
(3x + 1) - (x^2 - 6)
Distribute the negative into x^2 and -6 so you're equation now looks like this:
3 x + 1 - x^2 + 6
Combine like terms and arrange the equation into ax^2 + bx + c to get the final answer of:
-x^2 + 3x + 7

Answer:
y=
+ 
Step-by-step explanation:
6=4x+9y
First swap sides so that all variables are on the left side.
4x+9y=6
Subtract 4x from both sides.
9y=6-4x
Divide both sides by 9, this undoes the multiplication.
y=
Divide 6-4x by 9.
y=
+
