Answer:
Perpendicular
Step-by-step explanation:
2x - y = -7
2x + 4y = 2
-y = -2x - 7
4y = -2x + 2
y = 2x + 7
y = -1/2x + 1/2
Cannot be:
Parallel because the slope would otherwise be the same.
Same line because the equation is not proportional
So, they are perpendicular because a perpendicular line would be a negative and a reciprocal of the current line
Answer: 78 pounds
Explanation: if 1 kilogram is 2.2 pounds, just multiply the weight in kg by 2.2:
35.4 x 2.2 = 77.88
Round to nearest whole: 78.
So the dog is 78 pounds
Answer:
She used inductive reasoning. (False)
She used the law of detachment. (True)
Her conclusion is valid. (True)
The statements can be represented as "if p, then q and if q, then r." (False)
Her conclusion is true. (True)
Step-by-step explanation:
p = Two lines are perpendicular
q = They intersect at Right angles.
Given: A and B are perpendicular
Conclusion: A and B intersect at right angle.
According to the law of detachment, There are two premises (statements that are accepted as true) and a conclusion. They must follow the pattern as shown below.
Statement 1: If p, then q.
Statement 2: p
Conclusion: q
In our case the pattern is followed. The truth of the premises logically guarantees the truth of the conclusion. So her conclusion is true and valid.
(10)2 x (6)3 = 38
It will cost $38 for 2 adult's and 3 children's tickets.
