Write the sentence as a conditional statement. Two parallel lines lie in the same plane. If two lines are parallel, then the lin
olga nikolaevna [1]
<h2>Answer:</h2>

The conditional statement is:

  • If two lines are parallel then they lie in the same plane.
<h2>Step-by-step explanation:</h2>

We know that a conditional statement is the statement which is written in the form of:

        If  p then q  i.e.  p → q

where p is the hypothesis of the statement.

and q is the conclusion  of the statement which is based on the hypothesis.

Here we are given a statement as:

 Two parallel lines lie in the same plane.

i.e. the hypothesis of the conditional statement is:

Two lines are parallel.

and conclusion is: They will lie in the same plane

( Because if two lines lie in the same plane then we can't conclude that they will be parallel )

mrs_skeptik [129]

Answer:

Option B.

Step-by-step explanation:

The given table of values is

x         f(x)

-3       -2

-2        0

-1         2

0         2

1          0

2        -8

3        -10

4        -20

We need to find the interval for which the function f(x) is positive.

From the given table it is clear that the value of function f(x) is negative before -2 and after 1.

The function positive between x=-2 and x=1. So, we can conclude that the function f(x) is positive for the interval (-2,1).

Therefore, he correct option is B.

What will be the lowest common denominator for the fractions 2/3 and 4/5?
dusya [7]
To find the lowest common denominator between the fractions, what you need to do is simply write out the multiples of both 3 and 5 and find what multiple is common between both:

3,6,9,12,15
5,10,15

The multiple that is common and is the lowest in both would be 15.

The solution thus is B.15, it is the LCD for the fractions of 2/3 and 4/5.
