Hello! We see that 6 is the fixed amount. x represents the amount of something, and the solution makes a number $27. Let's make a real-world problem and then execute it.
Fawn has $6 in her piggy bank. She makes bracelets to sell to family & friends for $3 each. She wants to buy a video game that with tax, costs a little over $27. How many bracelets would Fawn have to sell in order to have enough money to buy the video game?
How to solve it:
So we have the expression of 3x + 6 > 27. First off, subtract 6 from both sides. 6 - 6 cancels out. 27 - 6 is 21. That's 3x > 21. Now, divide each side by 3 to isolate the x. 3x/3 cancels out. 21/3 is 7. There. x > 7. Fawn will have to sell more than 7 bracelets in order to have enough money for the game.
5x+13y=-13
13y=-5x-13
y=-5/13x-1
Y-intercept = -1
Slope = 5/13

Hello :
<span> x4 − 9x2 − 4x + 12 = x²(x²-9)-4(x-3)
=x²(x-3)(x+3)-4(x-3)
= (x-3)(x²(x+3)-4)
= (x-3)(x3+3x²-4)
= (x-3)(x-1)(x²+4x+4)
</span>x4 − 9x2 − 4x + 12 = (x-3)(x-1) (x+2)²
<span> potential roots is : 3 ; 1 :-2</span>
