Input 3y+11 for x
2(3y+11)-3y=16
6y+22-3y=16
3y= -6
Divide by 3 to isolate y
y=-2
Now for x....
x=3(-2)+11
=-6+11
=5
x=5
Coordinates (5,-2)
Circle A -- center(2, 0), radius 8 Circle A' -- center(-1, 5), radius 3
They are all larger than 90 degrees, and in a triangle they would all be obtuse angles.
Answer:
-$2.32
Step-by-step explanation:
Give that
The selling price per ticket is $9
And the number of tickets sold is 500
So,
There is one grand prize, three $300 second prize, and eleven $40 third prizes

= 6.68
Now the expected profit is
= $6.68 - $9
= -$2.32
220 miles in 4 h = 55 mph multiply this by 5280 to get feet per hour then divide this by 60 to get ft/min
