200+200+200+200+200+200+200+200+200
Answer:
(- 2, 6 )
Step-by-step explanation:
Given the equations
3x + 2y = 6 → (1)
y - x = 6 ( multiply through by 3 to clear the fraction )
2y - 3x = 18 ( add 3x to both sides )
2y = 18 + 3x → (2)
Substitute 2y = 18 + 3x into (1)
3x + 18 + 3x = 6
6x + 18 = 6 ( subtract 18 from both sides )
6x = - 12 ( divide both sides by 6 )
x = - 2
Substitute x = - 2 into (1) and solve for y
3(- 2) + 2y = 6
- 6 + 2y = 6 ( add 6 to both sides )
2y = 12 ( divide both sides by 2 )
y = 6
solution is (- 2, 6 )
Answer:
i don't know
Step-by-step explanation:
Mark on the grid all the points that fulfill all three inequalities.
Step-by-step explanation:
there is a right ∆ and a sector
area of right ∆ = .5×6×5 = 15 cm^2
area of sector = angle/360 * π * r^2
= 1/4 * π * 25 = 19.63 cm^2
area of the shape = 34.63 cm^2
10.x=1
11.3/4y+4 , x=1/5y+1/5
12.x=2
