Yes because say we are doing 2/10 if you divide 2 by 2 and 10 by 2 it will be 1/5 which equals the first one so yes they are.
Answer:
The parallel line has slope 
The perpendicular line has slope 
Step-by-step explanation:
Equation of a line:
The equation of a line has the following format:

In which m is the slope.
Parallel lines:
Parallel lines have the same slope.
Perpendicular lines:
If two lines are perpendicular, the multiplication of their slopes is -1.
In this question:
We have the following line:

Placing it in the general format


So this line has slope 
Parallel line:
Same slope, so the parallel line has slope 
Perpendicular line:
Multiplication of the slopes is -1. So



The perpendicular line has slope 
2(x-1)>-12
/2 /2
x-1>-6
+1 +1
x>-5
Answer:
62.8 units
Step-by-step explanation:
The formula for a cylinder πr²h. R being the radius and h being the height.
Therefore, plug in the numbers and solve.
π(2)²(5) = 20π = 62.8 units
Answer:
Y = 40
Step-by-step explanation:
Change 1/2 to 2/4
2/4 y + 6 = 3/4y - 4
subtract 2/4y
6 = 1/4y -4
add 4
10 = 1/4y
multiply by 4 to get fraction to 1y or y
y = 40
