Paige and Cindy have been saving money. Paige started with $350 in her savings and deposits $25 into her savings each week. Cindy savings is represented by the equation T =190+40w where T is total savings and w is the number of weeks. In how many weeks will Cindy have more money in her savings than Paige?

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,

x=-7

step-by-step explanation:

x+3=-10

-10+3=-7

x=-7

the solution, from the graphing of the two lines, is (3,2), i.e., x = 3, y = 2.
