<h3>What is axis of symmetry?</h3>
Axis of symmetry is a line that divides an object into two halves,thereby creation a mirror like reflection of either side of the object.
Now the given function is,
f(x) = 1/4 x^2 bx + 10
and axis of symmetry is at x = 6
Now the quadratic function in standard form is given as,
f(x) = a x^2 bx + c
By comprison we get,
a = 1/4
c = 10
Since axis of symmetry is a vertical line
x = -b/2a
Therefore,
6 = -b/2*(1/4)
-b = 6*2*(1/4)
or, b = -12/4
or, b = -3
Hence,The value of b is -3.

The equation be 50x = 17 then the value of x = 17/50.
<h3>How to find the value of x?</h3>
To estimate the value of x, bring the variable to the left side and bring all the remaining values to the right side. Simplify the values to estimate the result.
Let the equation be 50x = 17
Diving both sides of the equation by 50, we get
50x/50 = 17/50
x = 17/50
Therefore, the value of x = 17/50.

Step-by-step explanation:
i did the math lol
Step-by-step explanation:
a = age of Alex
l = age of Lucy
m = age of Megan
a + l + m = 126
l = 3a
l = m + 7
=>
a = l/3
m = l - 7
we are using that in the first equation :
l/3 + l + l - 7 = 126
l + 3l + 3l - 21 = 378
7l = 357
l = 357/7 = 51
a = l/3 = 51/3 = 17
m = l - 7 = 51 - 7 = 44
the ratio of the age of Lucy to Alex to Megan is
51 : 17 : 44
