Answer:

answer below

Step-by-step explanation:

when f(x+7)

moves the vertex to the LEFT not right

so the vertext would be (-5,-7)

when f(-x)

the graph is a reflection in y axis

so the vertex would be (-2,-3)

hope this helps!

A box contains a collection of triangular and square tiles. There are 2525 tiles in the box, containing 8484 edges total. How ma

AnnyKZ [126]

Let us consider the number of edges = x
we know that a triangle will have 3 edges and a square will have 4 edges. Using this details we can form an equation.
3x + 4x = 8484
7x = 8484
x = 8484/7
= 1212
Then
Number of square tiles = 1212/4
= 303
So there are 303 square tiles in the box. I hope the procedure is clear enough for your understanding. You can always use this method for solving similar problems.
