Answer: D
Step-by-step explanation:
To have a proportional relationship, the value of y divide by x has to have the same constant value and if you were to graph it, it has to go through the origin.
A is not proportional because it is not going through the origin.
B is also not proportional because it is also not going through the origin.
Now to find out if C is proportional divide the y value by x so see if they all have a constant change.
8/2 =4
16/4 = 4
24/8 = 3
32/ 12 = 2.6
This is also not proportional .
D. 3/2 = 1.5
6/4 = 1.5
12/ 8 = 1.5
18/12 = 1.5
This represents a proportional relationship because they all have a constant change
It looks like A {x|x > or = 0}.
But, your picture is blurry so it’s hard to see. If it’s a solid dot on the top left of the line and an arrow at the bottom right, then A is the correct answer. If that’s not what those are, sorry.
Answer:
You'd distribute the 2 to everything in the parenthesis. So, you'd do 2(4x) - 2(-11), which would then be 8x - (-22) = 19. You'd then add 22 to 19 to get 41. The only thing you can do from here is divide 8x by 41 to get 41/8 = x
Step-by-step explanation:
1. Adjacent angles have <em>a common side + vertex</em>.
2. Vertical angles are opposite sides of each other, and have <em>two common sides and one vertex</em>.
So,
13. Adjacent: they share a side + vertex.
14. Vertical: they are opposite to each other with the same two lines.
15. Neither: they do not share any sides or vertex.
16. Adjacent: they share a side + vertex.
There are tools for finding the measure of an angle. One of them is called a protractor. Some are very inexpensive while some are more expensive.
