Y=x^2-5
y=2x-5
y+5=2x
x=(y+5)/2
y=((y+5)/2)^2-5
y=(y^2+10y+25)/4-5
4y=y^2+10y+25-20
0=y^2+6y+5
0=(y+5)(y+1)
y= -5 or -1
y=2x-5 (y= -5 doesn't work for this one so use -1)
-1=2x-5
2x=4
x=2
Using these answers, you can choose answer D with reasonable certainty.
Answer: 4.3
Step-by-step explanation:
11x2=22
22/3= 7.3
7.3-3= 4.3
I think it would be commutative or associative because there is anything to distribute so it is NOT distributive
I think it might as while be C or sum
<span> -7 -7
------------------- = ---------------------
x^2 -2x -15 (x - 5)(x + 3)
x </span>≠ 5 and x ≠ -3
answer
<span>-3 and 5</span>
