Healthy Weight?

I’m seriously trying to eat healthier this year, after a long series of occasional half-assed attempts & fleeting fascinations with nutrition info in the past. I recently discovered the  Dr. Oz show too, which is now one of my favorite parts of day time TV.

We’ll see how this goes… heh, no but for real, so far.. not so bad. So who knows, this might actually be real progress, or so I hope. But yeah, either way it’s worth putting in the effort, cuz’ I’ve been spending a little too much money on vending machines & eating out in recent times, & there are a couple pieces of clothing I’m not ready to let go of simply cuz’ they don’t fit so nice anymore.

Now, being the neurotic numbers nerd that I am, I’ve found this BMI Calculator at the National Heart Lung & Blood Institute’s website handy, & possibly a little more trustworthy than others. However, we still know what they say, for a more acurate depiction consult a physician, did I mention I need to save money though?

Anyway, I’ve seen friends try the South Beach Diet, Weight Watchers, or just simply go vegan, & I’ve observed mild success as well as unenviable failure. As for me, I’ve pretty much concluded that there are only two food rules that work for me, especially if this is going to be a lifestyle change, & those are: that it’s not what I eat, it’s how much I eat (cuz’ there are certain guilty pleasures I doubt I’ll ever have the discipline to quit) & that variety’s the spice of life, I love the adventure of trying some new foods, & that’s probably my best chance at rounding out the load of vitamins & minerals we’re all supposed to be getting as well, right? & Please, if there’s something delicious you know of that you’re not sure I’ve tried, feel free to leave a suggestion in the comments.

linear functions (algebra)

linear functions: has the form of f(x) = ax + b  (a & b are constants)

constant functions: has the form y = c  (c is a real number)

identity functions: has the form y = x (a linear function where the slope (m) (or (a) ) = 1 & the y-intercept (b) = 0)

slope of a line: “rise over run” m = (y2 – y1) ÷ (x– x1)

slope-intercept form: y = mx + b (where m is the slope & b is the y-intercept)

rate of change: equals the slope of the function, if it is linear

two lines are parallel if they have the same slope

two (nonvertical & nonhorizontal) lines are perpendicular if their slopes are negative reciprocals of each other
