Vertical lines m and n are intersected by lines k and j. at the intersection of lines m and k, the bottom right angle is (x minus 30) degrees. at the intersection of m and j, the uppercase right angle is y. at the intersection of lines k and n, the bottom left angle is (x + 50) degrees. find the values of x and y that make k || j and m || n. x = ° y = °

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,

i would say b) is your answer
