Answer:
C -2 or 1
Step-by-step explanation:
So from the equation you have x^2-x-1=-2*x+1
x^2-x-1+2*x-1=0
x^2 +x -2 =0
D= 1^2 -4*(-2)= 1+8=9
x = (-1+-3)/2
So x is either (-1+3)/2=2/2=1
or (-1-3)/2=-2
70 because you would divide 150.8 by 2 and it gives you 75.4 but you have to round it and do v=4/3×3.14×70^3
Answer:
x = 5
Step-by-step explanation:
1. Distributive Property
(Do what's in the parenthesis first)
4x - 2x + 6 = -4 + 5x - 5
2. Combine Like Terms
2x + 6 = -9 + 5x
3. Take away 6 on both sides
2x + 6 - 6 = -9 - 6 +5x
It will give u.....
2x = -15 + 5x
4. Subtract 5x on both sides
2x - 5x = -15
It will give u.....
-3x = -15
5. Divide by -3 on both sides to isolate the variable
-3x / 3 = -15/-3
Now you get....
x = 5
2 negatives make a positive
Thats ur answer
Hope this helped!
What do you mean by find?
X - 5
Y - 7
That is the answer hope this helps !
