Ответ:
So, the length= 7x-16
and perimeter=x+x+7x-16+7x-16=48
So 16x=48+16+16
=80
x=5 will be the width,
hence length=7(5)-16
=19 inches

The initial value is the beginning output value, or the y-value when x = 0. The rate of change is how fast the output changes relative to the input, or, on a graph, how fast y changes relative to x. You can use initial value and rate of change to figure out all kinds of information about functions.
