Step-by-step explanation:
the rate of change is officially
(f(x2) - f(x1)) / (x2 - x1)
but for a line function (as we have here) this is totally easy : it is the slope of the line.
and that means it is the factor of x.
in our case this is -3/2.
because the slope of a line is the ratio "y coordinate change / x coordinate change". and that is exactly corresponding to the general rate of change definition above.
Answer:
Option "d" might be 11/13
Step-by-step explanation:
Red face cards=8. ( heart and Diamond)
Remove this 8 cards from 52 cards which gives
=>44
