The answer is 4. I hope this helped.
-2 = - x + x^2 -4 => x^2 - x - 4 + 2 = 0
x^2 - x - 2 = 0
a is the coefficient of x^2 => a = 1
b is the coefficient of x => b = - 1
c is the constant term => c = - 2
quadratic equation: [- b +/- √(b^2 - 4ac) ] / 2a =
= { 1 +/- √[ (-1)^2 - 4(1)(-2)] } / (2(1) = { 1 +/- √ (1 + 8) } / 2 = {1 +/- √9} / 2 =
= { 1 +/- 3} / 2
Answer:
$45.00
Step-by-step explanation:
it's the same thing, there is no context, so it pushes for me to believe that the answer is the same
Answer:
one solution
Step-by-step explanation:
-2x - 4 = x - 5
-3x - 4 = -5
-3x = -1
x = 1/3
y = 1/3 - 5
y = 1/3 - 15/3
y = -14/3
(1/3, -14/3)
