Answer:
-3 < b < 6
Step-by-step explanation:
6b < 36 or 2b + 12 > 6
b <
or 2b > 6 - 12
b < 6 or b > -3
Simplifying this becomes;
-3 < b < 6
Try this option:
1. if 8*x²+b*x+3=8*x²+p*x+q*x+3, then ⇒ b=p+q.
2. p*q = max_value (b²/2), if p=q=0.5*b, and p*q→-oo, if p>0 and q<0 or p>0 q<0.
3. example:
given 8x²+10x+3, the student rewrites it as a) 8x²+5x+5x+3 (5*5=25-max value); b) 8x²+0.01x+9.99x+3 (9.99*0.01=0.0999→0); c) 8x²-20x+30x+3 (p*q=-600).
answer: (-oo;0.5b²)
Answer:
53&8
Step-by-step explanation:
38-23=15
23+15+15=53
23-15=8
Answer: 
Step-by-step explanation:
We have the equation
where P represents the payment and w represents the amount of water used.
To calculate the monthly payment that corresponds to 12 units of water you must do
in the main equation and solve for the variable P.




X= -3
2/3x-10=12
Step 1: Add 10 to both sides.
2/3x=-2
Step 2: Multiply both sides by 3/2.
x= -3
