Answer:
Graph Y is the correct answer
Step-by-step explanation:
after 1 year, the price would be $200 * 1.15 = $230
After 2 years, the price would be $230 * 1.25 = $264.5
As you can see, the graph X and Z do not start at $200 in the first year so it will be eliminated
The graph W show that after 2 years the price is $300 but the second year must have the price of $264.5 so the only option left is graph Y.
Hope this can help!

Answer:

Step-by-step explanation:
The union of two sets P and Q, denoted as
is the set of all elements that are in the set P or in the set Q or in both sets P and Q.
Given:
P = {7, 8, 9, 10, 11}
Q = {1, 2, 3, 4, 5}
Then

When writing the union set, simply write all elements from both sets in on set.
Answer:
yes
Step-by-step explanation:
In front of every variable there is an invisible one which is being multiplied by the variable. This doesn't affect the variable because anything times one is still itself. The most common usage of the one is when combining like terms such as x+x. Since the equation is really 1x+1x, it would be 2x.
Answer:
7 sides
Step-by-step explanation:
formula for sum of interior angles
(n-2)× 180= 10 right angles
(n-2)× 180 = 900
n-2= 900÷180
n= 5+2
n= 7
