Answer:

The answer is below

Step-by-step explanation:

Transformation is the movement of a point from its initial location to a new location. Types of transformation is rotation, reflection, translation and dilation.

If a point A(x, y) is reflected over the x axis, the new point is at A'(x, -y). If a point B(x, y) is reflected over the y axis, the new point is at A'(-x, y).

Triangle A has vertex at (-4, -2), (-4, -5) and (-2, -5). If triangle A is reflected in the x axis to give triangle B, the vertex of triangle B is (-4, 2), (-4, 5) and (-2, 5).

If triangle B is reflected in the y axis to give triangle C, the vertex of triangle C is at (4, 2), (4, 5) and (2, 5). Hence the transformation is:

(x, y) ⇒ (-x, -y)

Does anybody know this one? 40= 15 - 9x- 2
asambeis [7]

Step-by-step explanation:

Simplifying 40 = 15 + -9x + -2

Reorder the terms: 40 = 15 + -2 + -9x

Combine like terms: 15 + -2 = 13 40 = 13 + -9x

Solving 40 = 13 + -9x

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '9x' to each side of the equation. 40 + 9x = 13 + -9x + 9x

Combine like terms: -9x + 9x = 0 40 + 9x = 13 + 0 40 + 9x = 13

Add '-40' to each side of the equation. 40 + -40 + 9x = 13 + -40

Combine like terms: 40 + -40 = 0 0 + 9x = 13 + -40 9x = 13 + -40

Combine like terms: 13 + -40 = -27 9x = -27

Divide each side by '9'. x = -3

Simplifying x = -3

Xsquared+11x+28+xsquared+13x+40
UNO [17]
X² + 11x + 28 + x² + 13x + 40

combine like terms

x² + x² = 2x²
11x + 13x = 24x
28 + 40 = 68

2x² + 24x + 68 is your answer

if you want it simplified: 

2(x² + 12x + 34)
   

hope this helps
