Answer:
8x - 3y = 12 _______( 1 )
5x = 2y + 7 _______( 2 )
On further solving ( 2 ), we get
5x - 2y = 7 _______( 3 )
Multiply ( 1 ) by 2
16x - 6y = 24 _______( 4 )
Multiply ( 3 ) by 3
15x - 6y = 21 _________( 5 )
Subtract ( 4 ) and ( 5 )
( 16x - 6y ) - ( 15x - 6y ) = 24 - 21
16x - 6y - 15x + 6y = 3
Put this in ( 2 )
5 ( 3 ) = 2y + 7
15 = 2y + 7
2y = 15 - 7
2y = 8
y = 8 / 2
Step-by-step explanation:
The area is 113.1. The formula is pie time the radius of the circle
Step-by-step explanation:
Looks like you want all equations converted into slope-intercept form.
- 2x + y = 2 ⇒ y = -2x + 2
- x + 2y = 4 ⇒ 2y = - x + 4 ⇒ y = - 1/2x + 2
- 2x - y = 2 ⇒ y = 2x - 2
- x - 2y = 4 ⇒ 2y = x - 4 ⇒ y = 1/2x - 2
