A) 3. This is the base number somebody would win without ever practicing.
B) y = 2x + 3. The slope of the line of best fit, depending on the points you pick, is roughly 2. Thus the answer for 13 would be 29.
Answer:
B) 7x + 8
Step-by-step explanation:
distribute 4 first to get:
12x + 8 - 5x
combine like terms to get:
7x + 8
Ummmm no I can’t tell you LOL
Answer: x = 2 ; -11 .

Explanation:
_____________________________________________
Given the equation:
_____________________________________________
x² + 9x −<span> 22 = 0 ; Solve for: "x" ;
_____________________________________________
Let us factor the "left-hand side" of the equation:
_____________________________________________
"x</span>² + 9x −<span> 22" ;
_____________________________________________
What are the factors of "-22"" that add up to "positive 9" ?
_____________________________________________
Let us list the factors of "-22" :
____________________________________________
-2, 11; </span>→ -2 + 11 = 9 ;<span>
-11, 2; </span>→ -11 + 2 = -9 ;<span>
____________________________________________
So we have: "-2" and "11" ;
____________________________________________
So; </span> "x² + 9x − 22" ; factors into " (x−2)(x + 11)" ;
____________________________________________
We have: (x−2)(x + 11) = 0 ;
So: x − 2 = 0 ;
Add "2" to each side of the equation;
x − 2 + 2 = 0 + 2 ;
x = 2 ;
___________________________________
x + 11 = 0 ;
Subtract "11" from each side of the equation;
x + 11 − 11 = 0 − 11 ;
x = -11 ;

Answer: x = 2 ; -11 .
