-1,7
0,-3
1,-7
5,47
Step-by-step explanation:
-x-=+
Answer:
0
Step-by-step explanation:
Since there is no negative sign with x, you could just take out the absolute signs.
So after you take them out you have:
x+1+x+2=3
Now, combine like terms:
x+x=2x
1+2=3
Combine into an equation:
2x+3=3
Subtract 3 on both sides:
2x+3-3=3-3
2x=0
Divide 2 on both sides:
x=0
(It would be undefined if it was )
But because it is , it would just be 0.
Hope this helped!
1.) add
2.) and
If you look at the chart you can see when you add B and D it equals E, therefore your answer is add.
Answer: x=0.25
Step-by-step explanation: 1−8x=−16x2
Simplify both sides of the equation.
−8x+1=−16x2
Subtract -16x^2 from both sides.
−8x+1−−16x2=−16x2−−16x2
16x2−8x+1=0
16x2+−8x+1=0
Use quadratic formula with a=16, b=-8, c=1.
x=
−b±√b2−4ac
2a
x=
−(−8)±√(−8)2−4(16)(1)
2(16)
x=
8±√0
32
x=0.25
