What's the vertex and axis of symmetry of y=2x+2)^2-4

Vertex: V=(-2,-4)

Axis of symmetry: x=-2

Step-by-step explanation:

y=2(x+2)^2-4

y=a(x-h)^2+k

Vertex: V=(h,k)

-h=2→h=-2

k=-4

V=(-2,-4)

Axis of symmetry: x=h→x=-2

the solution is 12x-6y

answer: 33 ( approx)

step-by-step explanation:

since, in the linear regression formula, the slope is the a in the equation y = b + ax ( by comparing it with the general equation of line y = mx + c )

where,

here given table is,

price ($), x   :           18         23       25       29       30       33

pairs sold, y :         16         13         10       8         6       2

so, ,   ,   ,

and   ,

thus, slop of the given line is,

⇒  

⇒   ≈ 33
