Answer:
Step-by-step explanation:
Hello!
We can use the factored form of a Quadratic to find an equation with 8 and -8 as our solution.
<h3>
Factored Form: 
</h3>
The value in each parenthesis should be 0. So 8 and -8 can be flipped and used for h and k.
This will give roots 8 and -8 for x.
A possible equation is .
If 5 is a factor of the number, then its ones place is either a 5 or a zero.
I am using "x" but alphabet letter does not matter.
#9
Words: x is greater than or equal to -4
Algebra: x ≥ -4
Possible solutions: 0,1,2
#13
Words: x is greater than 0
Algebra: x > 0
Possible solutions: 1,2,3
He'd have to sell 268 items
268x $1.50 = 402
$402 + $54 = $456
46.
3x + y = 2x +y
X+y=y
X= 0
3x + y + 2x +y = 4x+10
2y+x= 10
Y=5
