Answer:
It would be D.
Step-by-step explanation:
Domain is another word for x, basically. As range is for y.
Therefore, all of the x's are listed in option D.
The dependent variable is the number of times you have typed. This is because time is the independent (x) variable as the number of times you've typed is the dependent (y) variable.
Length=13
Height=10
Area=LxH/2 = 13x10/2= 130/2=65
Area=65
The simplest form of this sum is 670.
Answer:
The answer is (B) ⇒ Yes. AB is parallel to CD and AD is parallel to BC
Step-by-step explanation:
<em>There is an important fact about the parallel lines: </em>
- Parallel lines have equal slopes
<em>The rule of the slope of a line is:</em>
, where
and
are two points on the line
<em>Let us use the fact and the rule to solve the question</em>
∵ ABCD is a quadrilateral
∵ A = (0, 2) , B = (2, 6), C = (9, 6), D = (7, 2)
∵ The opposite sides are AB, CD and AD, BC
Find the slopes of the four sides to check the parallel sides
∵
∵ 
∵ The slope of AB = The slope of CD
∴ AB // CD
∵
∵ 
∵ The slope of AB = The slope of CD
∴ AD // BC
The correct answer is:
Yes. AB is parallel to CD and AD is parallel to BC ⇒ (B)
