Answer:
8
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) = (- 4, 6 ), thus
y = a(x + 4)² + 6
To find a substitute (- 3, 14) into the equation
14 = a(- 3 + 4)² + 6 ( subtract 6 from both sides )
8 = a
Thus the coefficient of the x² term is a = 8
Answer:
<h3>x = 2</h3>
Step-by-step explanation:
3x + 5 = 19 - 4x <em>subtract 5 from both sides</em>
3x = 14 - 4x <em>add 4x to both sides</em>
7x = 14 <em>divide both sides by 7</em>
x = 2
