Answer:
b = -6
Step-by-step explanation:
We use the general equation a*x^2 + bx + c = 0, the Quadratic Equation.
Compare it to 2x^2 - 6x - 20 = 0
b = -6 here
<span>Z + 1/z = 2
Multiply 1 by both sides
z+z=2
Add z and z together
2z=2
Divide both sides by 2
Final Answer: z= 1</span>
Answer:
0.85 < 8/9 < 0.92
Step-by-step explanation:
Hope this helps!!
You would divide negative 3 (-3) from both sides to keep the c by itself. When you divide a positive by a negative it becomes negative.
Dividing 15 by -3 would equal -5, so c = -5
It would be 0.2
Because
1 divided by 5 = 0.2
To check
0.2*5=1
Hope this helps
Have a great day/night
