The equation 3y = x + 1 would graph a line parallel to 3y = x + 5 ⇒ 1st
Step-by-step explanation:
Parallel lines have same slopes and different y-intercepts
To find which equation would graph a line parallel to 3y = x + 5
1. Put the equation in the form of y = mx + c
2. m is the slope of the line and c is the y-intercept
3. Look for the equation which has the same values of m and different
values of c
∵ 3y = x + 5
- Divide each term of the equation by 3 to put the equation in the
form of y = mx + c
∴ y =
x + 
∴ m = 
∴ c = 
The first answer:
∵ 3y = x + 1
- Divide each term of the equation by 3
∴ y =
x + 
∴ m = 
∴ c = 
∵ The two equations have same slope m = 
∵ The two equations have different y-intercepts c = 
and c = 
∴ 3y = x + 5 and 3y = x + 1 represent two parallel lines
The equation 3y = x + 1 would graph a line parallel to 3y = x + 5

-- "Perimeter" means all the way around, all four sides.
-- That's two lengths and two widths.
-- So one length and one width is half of the perimeter.
-- If the perimeter is 16-ft, then one length + one width is 8-ft.
-- If the width is 5-ft, then the length is (8 - 5) = 3-ft.
We have c=3.7 cm, B=97 degrees, area Δ=22.4 sq cm, and we'll call A the vertex opposite a and C the vertex opposite c=3.7 as usual.
Δ = (1/2) ac sin B
a = 2Δ / (c sin B)
Now we have a Law of Cosines situation for b
b² = a² + c² - 2 a c cos B
We could substitute for a general solution but let's just plug in the numbers,
a = 2(22.4) / (3.7 sin 97) = 12.199
b = √(a² + c² - 2 a c cos B)
b = √(12.199² + 3.7² - 2 (12.199)(3.7) cos 97) = √173.507 = 13.17
