Neither parallel nor perpendicular
To get the circumference you times 3.14 which is PI and times PI by diameter to get the circumference
Answer:
x = 6 , y = -2
Step-by-step explanation:
2 x + 3 y = 6 (Equation 1)
x + y = 4 (Equation 2)
<u>Solving by substitution</u> :
(Equation 2) ⇒ y = 4 - x
<u>Substitute y by 4 - x in (equation 1)</u> :
2 x + 3 (4 - x) = 6
Then
2 x + 12 - 3x = 6
Then
12 - x = 6
Then
12 - 6 = x
Then
x = 6
<u>We obtain</u> :
y = 4 - x and x = 6
Then
y = 4 - 6
= -2
