Answer: Many weight loss coaches use the term âstarvation modeâ to describe your bodyâs natural response to protect itself when you donât eat enough for extended periods. When you regularly eat too little food to provide your body with the necessary nutrients, it perceives itself to be in danger from starvation.
If you can move an entire design in one of these ways, and that design appears unchanged, then the design is symmetric. If you can reflect (or flip) a figure over a line and the figure appears unchanged, then the figure has reflection symmetry or line symmetry. The line that you reflect over is called the line of symmetry. A line of symmetry divides a figure into two mirror-image halves. The dashed lines below are lines of symmetry: The dashed lines below are not lines of symmetry. Though they do cut the figures in half, they don't create mirror-image halves. You can use a Mira (image reflector) or simply the process of cutting and folding to find lines of symmetry.
The axis of symmetry is also defined by the following equation: x = - b /2 a. Remember, a quadratic function has the following form: y = ax 2 + bx + c. Follow 4 steps to use an equation to calculate the line of symmetry for y = x 2 + 2 x. 1  Identify a and b for y = 1 x 2 + 2 x. a = 1; b = 2. 2  Plug into the equation x = - b /2 a. 3  x = -2/(2*1). 4  Simplify. 5  x = -2/2. 6  The line of symmetry is x = -1.
