Use the quadratic formula to solve x^2 -5x+4 then describe the solution

see explanation

Step-by-step explanation:

Equate the quadratic to zero

x² - 5x + 4 = 0 ← in standard form

with a = 1, b = - 5, c = 4

Using the quadratic formula to solve for x

x = ( -(- 5) ± ) / 2

  = ( 5 ± ) / 2

  = ( 5 ± 3 ) / 2

  x = or x = , hence

x = 1 or x = 4

The solutions are real, rational and distinct

i do not know the answer

step-by-step explanation:

a) y = -3x +2

b) y = 1/2x -6

these 2 can be combined into one equation.

-3x +2 = .5x -6

8 = 3.5x

x = 8 / 3.5 = 2.2857142857

y = -3 * (8 / 3.5) +2

y = (-24 / 3.5) + 2

y = -4.8571428571
