Each ordered pair is (x,y). Determine the coordinates by substitution.
for (15,y):
y=1/3 * 15 - 9
y=-4
for (x,-6):
-6=1/3x -9
1/3x=3
x=9
-20+1= -19
-19/2= -9.5
Check:
-9.5x2= -19
-19-1= -20
Answer:
(40/3)*pi
Step-by-step explanation:
lets first find the area of the little circle
A=pi*r^2
A=pi*3^2
A=9pi
Now, lets find the area of the big circle
A=pi*r^2
A=pi*(3+4)^2
A=pi*7^2
A=49pi
now lets subtract the area of the little circle from the area of the big circle
49pi-9pi=40pi, now we found the area of the "bagel)
lets find what portion of the bagel is the shaded region
120/360=1/3
now lets multiply the bagel area by the fraction
40pi*(1/3)=
(40/3)*pi or (40*pi)/3
Answer:
21
Step-by-step explanation:
lol
63/12 = 4.2
4.2 x 12 = 50.4
x = 50.4
