5/2-d-2/4=?
? = 0

Simplify ➡ 1/2
1 ÷ 2 = 0.5

5/2 - D - 1/2 = ?
Remember I said the mystery number ( ? )is '0'

d(2)/ 2

2(d) - 1 / 2

5/2 - 2(d) - 1 / 2

Simplify ➡ 5/2
5 ÷ 2 = 2.5

6 - 2(d)

3 - D = 0

'd' is a negative for now.

So, -d + 3 = 0
- 3d - 3
-------- ------
-3 -3
× 1 × 1
--- ----
-3 -3

Number of solutions: One

Therefore, your answer would have to be
"d" is 3; d = 3

The graph of y=x^2 was transformed to Y= -(x+3)^2 +5. Describe all transformations applied to the original function and determin

Hey there!

1. The graph was flipped vertically and now opens downward.

We know this because there is a negative sign in front of the equation:

$y=$ $\boxed-$ $(x+3)^2+5$

2. The graph was moved 3 units to the left.

We know this because there is 3 added to x inside of the parenthesis. Remember, inside (parenthesis) is opposite and acts on x, outside (parenthesis) is same and acts on y.

$y=-(x\boxed{+3})^2+5$
