Answer:
13x+14
Step-by-step explanation:
2(3x+4)+6+7x
Distribute:
=(2)(3x)+(2)(4)+6+7x
=6x+8+6+7x
Combine Like Terms:
=6x+8+6+7x
=(6x+7x)+(8+6)
=13x+14

Step-by-step explanation:
The equation of a parabola in vertex form is
y = a(x - h)² + k
where (h, k) are the coordinates of the vertex and a is a multiplier
Here (h, k) = (3, 1), hence
y = a(x - 3)² + 1
To find a substitute (- 2, - 4) into the equation
- 4 = a(- 2 - 3)² + 1
- 4 = 25a + 1 ( subtract 1 from both sides )
25a = - 5 ( divide both sides by 25 )
a = -
= - 
y = -
(x - 3)² + 1 ← in vertex form
