Practicing Perimeter with Equations

The perimeter of the triangle is 40 units. Write an equation for the perimeter of the triangle.

Once you have written the equation, solve the equation for the value of x. Type the value of x in the blank provided on the next slide!

Fill in the Blank

You found the value of x from the previous slide. Type your value of x here.

Multiple Choice

Solve the equation for the value of x:

 $2x+8=16$  

• x = 10

• x = 6

• x = 4

• x = 2

Fill in the Blank

When you evaluate an expression, you are taking the given x-value and plugging it in to the given expression. For this problem, evaluate the expression below when x = -2. Type your numeric answer ONLY!

 $x^2+7x\ -\ 9$  

Multiple Choice

Given the graphed line with two points identified, what is the slope of the line that is parallel to the given line?

• 3/4

• 2/3

• 1/2

• 1/3

Reflections and Translations - REMINDERS!

Reflections:

Reflections over the x-axis change the y value in the coordinate.

Reflections over the y-axis change the x value in the coordinate.

Translations:

Translations slide the graph left/right (x value changes) and up/down (y value changes)

Translations Practice with a Graph

On the graph, the red triangle has been translated (a slide) so that it now resides as A'B'C' (blue triangle).

What is the translation that moved the red triangle to the blue triangle? Provide your answer (two part movement) on the next slide.
