Which of the following is equal to 2? * A. (6 + 4 ÷ 2) – 1 × 3
B. 6 + (4 ÷ 2) + 1 × 3
C. (6 + 4) ÷ 2 – 1 × 3

(6 + 4) divided 2 - 1 x 3 is equal to 2

Step-by-step explanation:

Step-by-step explanation:

The axis of symmetry is vertical, so the parabola is vertical.

Vertex-form equation for a vertical parabola with vertex (h,k):

y = a(x-h)² + k

axis of symmetry: x = h

Apply your data and solve for h, k, and a.

vertex (-1,7)

h = -1

k = 7

y = a(x+1)² + 7

(0,10) is a point on the parabola

10 = a(0+1)² + 7

a = 3

The equation becomes

y = 3(x+1)² + 7
