When I think of a number, double it, then add 7, I get 25. What number did I think of? ( Hint: Let the number be x)o

Hey there!

The answer is

We will start by forming an equation to solve this.

So we are starting with a number, , then doubling it and adding , which gives us 25.

So:

Now we solve this equation:

Have a super awesome day!

step-by-step explanation:

here's what happens:

1) the graph of f   = x^2 is shifted 2 units to the right.

2) the resulting graph is reflected in the x-axis, so that the parabola now opens down.

3) this final result is transformed up by 5 units.

lockers 1, 4, 9, 16, 25, 40, and 49 are open
