Answer: y=0 and x=3
Step 1: Solve for x in 2x+9y=6.
(Subtract 9y from both sides)
( Divide both sides by 2)
Step 2: Replace x with 3-4.5y
Step 3: Solve for y
(By looking at this, we can determine that y=0)
Step 4: Replace y with 0
(Divide both sides 2)
Therefore, y=0 and x=3
It is 1082.
I hope it helps, you can do more on a calculator. :)))
Volume of a cylinder = Height x base are
H = 6.2 m
Bae are = π.R² ; Diameter =4.4 m, then Radius = 2.2 m
Base area = π(2.2)²
And Volume=:
V= (6.2).(π,2.2²) = (6.2).(π)(.4.84) = 30.008.π ≈ 94.2 m³
Answer:
9x
Step-by-step explanation:
(x² + 2x) - (x² - 7x) ← distribute parenthesis
= x² + 2x - x² + 7x ← collect like terms
= 9x
