1. Identify the vertex, focus, and directrix. y =1/24x²

O vertex (0, 0); focus (0, 6); directrix at y = 6
O vertex (0, 0); focus (6, 0); directrix at y = 6
O vertex (0, 0); focus (6, 0); directrix at y = -6
O vertex (0, 0); focus (0, 6); directrix at y = -6

i am sorry it just submitted an answer but the answer is 365 boys. hopes this

step-by-step explanation:

what is the answer?

b. 153 students do not participate in sports and seventy-five 12th graders were surveyed

5=812a+9+3

step 1: simplify both sides of the equation.

5=812a+9+3

5=(812a)+(9+3)(combine like terms)

5=812a+12

5=812a+12

step 2: flip the equation.

812a+12=5

step 3: subtract 12 from both sides.

812a+12−12=5−12

812a=−7

step 4: divide both sides by 812.

812a /812 = -7/812

a= -1/116

so the answer is

a=   -1/116
