6k + 2 = 8
Isolate the 8. Do the opposite of PEMDAS.
Note the equal sign. What you do to one side you do to the other.
Subtract 2 from both sides
6k + 2 (-2) = 8 (-2)
6k = 8 - 2
6k = 6
Isolate the k, divide6 from both sides.
6k/6 = 6/6
k = 6/6
k = 1
1 is your answer.

The right triangle with angle 45 ° has adjacent leg 9 feet
So the opposite leg is calculated from
tan 45 = opposite leg / adjacent leg ⇒ adjacent leg = 9 tan 45 = 9.
That is the distance bc.
The right triangle with angle 60° has adjacent leg 9 and opposite leg (x+9), where x is the distance ab.
Then tan(60) = (x+9) / 9 ⇒x+9 = 9 tan(60)
x + 9 = 15.59
x = 15.59 - 9 = 6.59
Answer: 6.59 feet
The parabola is going downwards.
The equation for the axis of symmetry is x = -1.
The vertex is at -1,9
The x-intercepts are at -4, 2
