Let the number be x
1/2 x + 69 = 74
1/2 x= 74 - 69
1/2 x = 5
x = 2*5
x= 10

Answer:

10

Step-by-step explanation:

let the number be n then half the number is \frac{1}{2} n , so

\frac{1}{2} n + 69 = 74 ( subtract 69 from both sides )

\frac{1}{2} n = 5 ( multiply both sides by 2 to clear the fraction )

n = 10

Thus the number is 10

Vertex is (h,k)
se see vertex is (1,-4)
y=a(x-1)^2-4
find a
another point is (4,-2)

-2=a(4-1)^2-4
-2=a(3)^2-4
-2=9a-4
add 4
2=9a
