Answer:

Slope = \frac{-1}{3}

Step-by-step explanation:

(x₁ , y₁) = (-9 , -4)   & (x₂ ,y₂) = (-3, -6)

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

         = \frac{-6-[-4]}{-3-[-9]}\\\\= \frac{-6+4}{-3+9}\\\\= \frac{-2}{6}\\\\= \frac{-1}{3}

iris [78.8K]

Answer: 3 7/8 feet

Step-by-step explanation:

From the question, we are informed that Darla sees a duck and a fish at a pond and that the duck is 2 1/2 feet above the surface of the pond while the fish is 1 3/8 feet below the surface of the pond.

The distance, in feet, between the duck and the fish will be calculated as:

= 2 1/2 - (-1 3/8)

= 2 1/2 + 1 3/8

= 2 4/8 + 1 3/8

= 3 7/8 feet

The distance, in feet, between the duck and the fish is 3 7/8 feet

Solve using the quadratic formula:
timurjin [86]

Answer:

\boxed{x_1 = \frac{7 + \sqrt{5} }{2} ~~or~~x_2 = \frac{7 - \sqrt{5} }{2} }

Step-by-step explanation:

x^2 - 7x + 11 = 0

x^2 - 7x = -11

(x - \frac{7}{2} )^2 - \frac{49}{4}  = -11

(x - \frac{7}{2} )^2 = -11 + \frac{49}{4}

(x - \frac{7}{2} )^2 = \frac{5}{4}

x - \frac{7}{2} = \pm \sqrt{\frac{5}{4}}

x = \frac{7 \pm \sqrt{5} }{2}
