D = | -12 - 9 | = -21
d = | -2 - (-7) | = 5
d = | 25 - (-1) | = 26
Answer:
He initially has $50 on his card.
For each night that he goes to play, $10 are discounted from the card, then if he went x nights to play, the amount of money that there is in the card is:
b(x) = $50 - $10*x
Now, notice that x must be a whole number because this measures the number of nights that he went to play, and we can not have rational numbers to describe this.
Then the domain of this function will be discrete (and this implies that the range must also be discrete)
Where the possible values of x are:
{0, 1, 2, 3, 4, 5}
(after x = 5, there is no more money in the card)
And the possible values of b(x) are:
{$0, $10, $20, $30, $40, $50}
Answer:
2*12 = 24
12*2 = 24
24/2 = 12
24/12 = 2
Step-by-step explanation:
You have two groups called feet. In each group (foot), you have 12 inches. You would use the fact family 2, 12, and 24 to find the number of inches in 2 feet because you have 2 feet, each foot contains 12 inches, and 2*12 is 24.
