The answer is y=24x I hope this helps
Step-by-step explanation:

B is equal to 51 because angles in a right angle add up to 90
The vertex is the minimum or the maximum point of the parabola.
<em>x and f(x) represent the horizontal and the vertical coordinates of the vertex.</em>

The standard form of a parabola is

The x coordinate of the parabola is calculated using:

The value of the x-coordinate is then plugged in, into the equation to calculate the y-coordinate, as follows:

At the end of the calculation,
x and f(x) represent the horizontal and the vertical coordinates of the vertex.
Take for instance:

The x-coordinate of the vertex is:




The y-coordinate is:



So, the vertex of
is (-1,11)

Answer:
The two locker numbers are 68 & 69.
Step-by-step explanation:
Let one locker number be x then other will be , then other will be x+1.
We are given that sum is 137.
x+x+1=137
2x+1=137
2x=136
x = 68
The two locker numbers are 68 & 69.
