Graph a line with a slope of -2/5 that contains the point -3, 5

He expression 2(l + w) is used to calculate the perimeter of a rectangle, where l is length and w is width. if the length is fraction 2 over 3 unit and the width is fraction 1 over 3 unit, what is the perimeter of the rectangle in units? fraction 2 over 3 unit 1 unit 1fraction 2 over 3 units 2 units

What is the definition of exponential decay?

Hi, can anyone show me how to do this problem? 100 points for this. in advance
