Idk srry ...........................................
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
Answer:
A = 78.5 cm^2
Step-by-step explanation:
The area of a circle is given by
A = pi r^2
We know r =5 and pi = 3.14
A = 3.14 (5^2)
A = 3.14 (25)
A = 78.5 cm^2
Answer:
<h2>= 1.268</h2>
Step-by-step explanation:
= (3 + √3) (2 - √3)
= 6 - 3√3 + 2√3 - 3
= 3 - 3√3 + 2√3
= 3 - √3 (3 - 2)
= 3 - √3
= 3 - 1.732 ...... (√3 = 1.732)
= 1.268
