Answer: We can get all of the answers by looking at the parts of the graph.
1) The height of the board is about 10, that is all the way at the left.
2) The maximum height is 10.8 at the vertex of the graph.
3) The time at the vertex is 0.4 seconds.
4) The diver enters the water after 1.9 seconds, it is at the bottom right.
Answer: Each book is 1,800 grams.
Explanation:
You have an empty box which is 1,800 grams. After you put the books in, it's 9 kilograms. There are 9,000 grams in 9 kilograms, and 1,800 grams were already there before you put the books.. so just do 9,000 - 1,800 which equals 7,200. Then divide 7,200 by 4, because there are 4 books with equal mass. 7,200 divided by 4 = 1,800.
Math. ;) Hope this helps! (If I got it right ofc)
Answer:
x=4
Step-by-step explanation:
you subtract the x on both sides
6=2x-2
then you add 2 on both sides
8=2x
then divide 2 on both sides
and you get x=4
Answer:
| x-13| = 5
Step-by-step explanation:
(We need an absolute value equation with solutions of 8 and 18
| x-y| = z
We get a positive and negative solution
x-y =z x-y = -z
Solve for x
Add y to each side
x-y+y = z+y x-y+y = -z+y
x = z+y x = -z+y
Let the larger one equal 18 and the smaller one equal 8
z+y = 18 and -z+y = 8
Add the two equations together to eliminate z
z+y = 18
-z+y = 8
-------------------
2y = 26
y = 13
Now we need to find z
z+y = 18
z+13 = 18
z = 18-13
z=5
Putting this back into the absolute value equation
| x-13| = 5
I believe that it is the second one. Intersection, union.
