The vertex is (1,-3)

EXPLANATION

The given parabola has equation:

${y}^{2} + 6y + 8x + 1 = 0$

We group the variables to obtain:

${y}^{2} + 6y = - 8x - 1$

We complete the square to get,

${y}^{2} + 6y + {3}^{2} = - 8x - 1 + {3}^{2}$

${(y+ 3)}^{2} = - 8x +8$

${(y+ 3)}^{2} = - 8(x -1)$

The vertex is of the parabola is (1,-3)

If the mean of a set of 12 number is 13 then the sum of the number is?

rjkz [21]

Answer:

156

Step-by-step explanation:

Let the sum of the set of numbers = S

So....the mean would be calculated as the sum of the set divided by its number of entries, or :

S / 12 = 13 ....... multiply both sides by 12

S = 13 * 12 = 156 .....so.....the sum is 156
