For the equation:
-1=5 x^2 - 2 x
5 x^2 - 2 x + 1 = 0, then we substitute: a=5, b=-2, c =1
to discriminant formula: D= b^2 - 4 a c = (-2)^2 - 4 * 5 * 1 = 4 - 20 = - 16
Answer:
The discriminant is equal to -16 which means the equation has no real number solutions.
The solution to this system of equations is (-4,0)

When you want to find the slope of the perpendicular line, all you have to do is flip the known slope upside down and make it negative. You know that
slope is 3 and you know
is perpendicular. So, just flip 3 upside down into
and then make it negative,

x + 4.
Answer:
x = 68/33
Explanation:
Step 1: Simplify both sides of the equation.
Step 2: Subtract 2/5x from both sides.
Step 3: Add 80 to both sides.
Step 4: Multiply both sides by 5/198.
