Kevin had $640 in his savings account at the beginning of the semester. He has been withdrawing $40 each week for meals. He would like to have at least $200 at the end of the semester. Kevin wants to know for how many weeks in all he can withdraw $40 and still have at least $200 left. He solves the inequality 640−40w≥200 to get w≤11 .

How should Kevin interpret his solution?

to find the perimeter of the rectangle this is the expression:

x-9+x-9+3x-4+3x-4=138

if we simplify it:

8x-26=138

remember, 138 is what it all adds up to

the length is 11.5cm

the width is 57.5cm

the area is 661.25cm^2

the answers might not be correct use at own risk

correct choice is b

step-by-step explanation:

when you calculate the average rate of change of a function, you are finding the slope of the secant line between the two points. for the function the average rate of change from point to point can be calculated as

to find the average rate of change from day 2 to day 10, note that at day 2, 8 houses were sold, so a(2,8) and at day 10, 2 houses were sold, so b(10,2). thus,
