Answer:
x = -8, y = 6
Step-by-step explanation:
x + 2y = 4 ------(1)
x + y = - 2
y = - x - 2 ----------(2)
Substitute y in (1)
x + 2(- x - 2) = 4
x - 2x - 4 = 4
- x = 4 + 4
x = -8
Substitute x in (2)
y = - (- 8) - 2 = 8 - 2 = 6
Will you will have to babysit like 6 hours cause you got pay only 9 from the car wash and 10x5=50 + the 9 car wash is 59 only and u will need the .95 so u will need 6 hours of babysitting for the .96

Answer:
∅1=15°,∅2=75°,∅3=105°,∅4=165°,∅5=195°,∅6=255°,∅7=285°,
∅8=345°
Step-by-step explanation:
Data
r = 8 sin(2θ), r = 4 and r=4
iqualiting; 8.sin(2∅)=4; sin(2∅)=1/2, 2∅=asin(1/2), 2∅=30°, ∅=15°
according the graph 2, the cut points are:
I quadrant:
0+15° = 15°
90°-15°=75°
II quadrant:
90°+15°=105°
180°-15°=165°
III quadrant:
180°+15°=195°
270°-15°=255°
IV quadrant:
270°+15°=285°
360°-15°=345°
