No not always, because x could be a smaller number than y which would make it an negative. If x is bigger than y most likely it will be, but not always.
Answer:
1.5
Step-by-step explanation:
k= y/x
y= 12-4.5 =7.5
x= 8-3 = 5
k = 7.5/5 = 1.5
Answer:
The correct option is option number 4. Parallel lines are defined as lines that never have one point in common.
Step-by-step explanation:
Parallel lines: Parallel lines are the lines that will never cross each other. As they never meet, so they won't have a common point.
On the other hand, the other options are incorrect. This is because,
Perpendicular lines: Perpendicular lines are the lines that make 90 degrees angle with each other.
Skew lines: Skew lines are the lines that are not present on the same plane.
Coplanar lines: Any lines which are known to occur on the same plane are termed as coplanar lines.
Square both sides to get the binomial out of the square root:
(√(2x + 8))² = (2)²
2x + 8 = 4
2x = 4 - 8
2x = - 4
Divide both sides by 2 to isolate the variable X:
x = - 4 / 2
x = - 2
Your answer is option C.
