Answer:
Not parallel.
Step-by-step explanation:
If the slopes are the same they are parallel.
So we convert each one to slope-intercept form:
-5x - 4y = -3
-4y = 5x - 3 Divide both sides by -4:
y = -5/4 x + 3/4.
Slope = -5/4.
-5x – 5y = -3
-5y = 5x - 3 Divide both sides by -5:
y = -1 x + 3/5.
Slope = -1.
The slope are different - so NOT parallel.
Answer:
Step-by-step explanation:
Simplifying
W + -2 + 2w = 6 + 5w
Reorder the terms:
-2 + W + 2w = 6 + 5w
Solving
-2 + W + 2w = 6 + 5w
Solving for variable 'W'.
Move all terms containing W to the left, all other terms to the right.
Add '2' to each side of the equation.
-2 + W + 2 + 2w = 6 + 2 + 5w
Reorder the terms:
-2 + 2 + W + 2w = 6 + 2 + 5w
Combine like terms: -2 + 2 = 0
0 + W + 2w = 6 + 2 + 5w
W + 2w = 6 + 2 + 5w
Combine like terms: 6 + 2 = 8
W + 2w = 8 + 5w
Add '-2w' to each side of the equation.
W + 2w + -2w = 8 + 5w + -2w
Combine like terms: 2w + -2w = 0
W + 0 = 8 + 5w + -2w
W = 8 + 5w + -2w
Combine like terms: 5w + -2w = 3w
W = 8 + 3w
Simplifying
W = 8 + 3w
The weight is 62 and a half lb per cubic feet.
Answer:
