Y+10=0*(x+10)
That is the answer I believe
Answer:
(a)x= y+14
(b)x=34, y=20
Step-by-step explanation:
Let the number of tickets sold by your friend = y
Let the number of tickets sold by you=x
You sell 14 more tickets than your friend sells.
Number of tickets sold by you, x= y+14
(a) The system of linear equations that represents this situation is: x= y+14
(b)Together, you and your friend sell a total of 58 tickets.
x+y=54
Since x= y+14
(y+14)+y=54
2y+14=54
Subtract 14 from both sides
2y+14-14=54-14
2y=40
Divide both sides by 2
y=20
Recall, x= y+14
x=20+14=34
You sell 34 tickets and your friend sells 20 tickets.
Answer:
1017.36m
Step-by-step explanation:
The formular for finding the total surface area of a sphere is 4πr²
Where π is 3.14 and from the question r is 9m
4X3.14X9²
4X3.14X81
1017.36m
6.42 pm is the answer. You can think backward 8 hours before 2:12 am, which is 6:12pm. Now, go 'forward' a half an hour, to 6:42pm. Answer: 6:42pm.
