Answer:

Step-by-step explanation:

Do you know how to use the quadratic formula?

x = \frac{-b +/- \sqrt{b^2 - 4*a*c} }{2*a}

a = 5

b = -1    

c = 3

x = \frac{1 +/- \sqrt{1 - 4*1*3} }{2}\\x= \frac{1 +\sqrt{-11} }{2}\\x = \frac{1 +/- i\sqrt{11} }{2}

Kazeer [188]

Answer:

D

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Calculate m using the slope formula

m = \frac{y_{2}-y_{1}  }{x_{2}-x_{1}  }

with (x₁, y₁ ) = (- 4, 29) and (x₂, y₂ ) = (0, 28) ← 2 ordered pairs from the table

m = \frac{28-29}{0+4} = - \frac{1}{4}

The line crosses the y- axis at (0, 28 ) ⇒ c = 28

y = - \frac{1}{4} x + 28 ← equation of line → D
