If the slope of f(x) was multiplied by -2/7 and the y-intercept was decreased by 7 to create a new fuction g (x) describe the transformation?

The function would do 3 things

1. flip horizontally, because of the negative applied to the slope

2. widen, because of a fractional slope between -1 and 0 (-2/7 makes the rise shorter than the run, so the function widens by going 7 units out for every 2 units down)

3. shift down 7 units, because the initial y-intercept would be changed from, say, 8 to 1. this would bring the graph downwards by 7 units

What is your question?

You have 2 sides that are 2 cms and you have 6 sides that are 1/2 cm and you have 4 sides that are 1 cm. the smallest sides are 1/2 the medium sized sides are 1 and the smallest are 1/2. so to find the perimeter you have to add them all up together so your answer will be 11 cm's
