X = 13.

Because you want x by itself, to need to remove the +8. So, you must do the opposite to BOTH sides. The opposite of +8 is -8, and 21-8=13. Therefore​, x=13.

Which glide reflection describes the mapping Triangle ABC to DEF
iVinArrow [24]

Answer:

The correct option is A.

Step-by-step explanation:

The correct option is A.

If u notice the second transformation it would shift  triangle ABC 3 units to the left and reflect it across x = 4 so this will not map ABC into DEF.

If u notice first transformation it will shift triangle ABC 7 units down and reflect it across x=4 so this will map ABC into DEF.

Thus option A is correct....

A certain library charges a flat fee of $5 for any overdue book for the first x days the book is overdue, and an additional fee
bearhunter [10]

Answer: 5 (x > 12) or 5 + m(12 - x) (x < 12)

Step-by-step explanation:

flat fee $5 for first x days +

m dolars per day after x days

So, if x > 12, for 12 days the fee is $5 because it is a flat fee that do not depend of the numbers of day.

But, we do not know how many days x is, so

if x < 12, a person will pay, for 12 days, the m times the difference of the days passed x:

5 + m(12-x)

A phone sales associate makes $54 each day that he works and makes approximately $34 in commission for each phone that he sells.
den301095 [7]

Answer:

8

Step-by-step explanation:

Since the associate makes $54 every day he works, we know he makes a minimum of $54. So, from his goal of $326, we can subtract the minimum to find how many phones he must sell.

326 - 54 = 272

So, he must sell $272 worth of phones. For every phone he sells, he makes $34. So, we can find how many phones he must sell by dividing the goal by the cost of each phone.

272 / 34 = 8

So, he has to sell 8 phones, at the very least, in order to achieve his goal.

Tossing a coin and getting heads or tails
Luden [163]
When tossing a coin, the event of getting head and tail are mutually exclusive events. Because the probability of getting head and tail simultaneously is 0. In a six-sided die, the events “2” and “5” are mutually exclusive events. We cannot get both events 2 and 5 at the same time when we threw one die.
