Answer:
$24 sold
Step-by-step explanation:
Omar sold 4
(4x6=24)
Debra sold 3
(3x8=24)
In a standard deck of cards, there are 13 diamond cards and 39 non diamonds. To choose 3 diamonds from 13 cards would be equivalent to 13*12*11 as there are less cards to choose from each time you remove a card. To choose two non diamonds from the other non diamonds cards would be equivalent to 39*38, taking into account the number of cards you remove each time you pick out one card. Hence the total number of ways is 13x12x11x39x38.
The domain is the values of x from the x-axis that 'cover' the given function.
Look at the end points of the graph and the corresponding values of x on the x-axis. These go from - 5 to 4
Thus the domain is x ∈ [- 5, 4 ] ← domain
The square bracket indicates that the values of - 5 and 4 are included in the domain
Whereas (- 5, 4 ) indicates that - 5 and 4 are not included but all values in between are
The range is the values of y from the y-axis that cover the given function
Look at the minimum value and maximum value of the function along the y-axis
The minimum is 0 and the maximum is 5
range is y ∈ [0, 5 ]
To determine the value of y when x = -3
Locate x = - 3 on the x-axis, move up vertically until the line representing the function is met, and read off the corresponding y value to the right on the y-axis
The value of f(x) when x = - 3 is 2
