Answer:
So value of x = -1 and value of y = 1
Solution Set (-1,1)
Step-by-step explanation:
x+y =0
x-y +2 =0
We need to solve these equations to find value of x and y
x+y =0 eq(1)
Add -2 on both sides
x-y = -2 eq(2)
Add equation 1 and 2
x+y = 0
x-y =-2
______
2x = -2
x = -2/2
x = -1
Now, put value of x = -1 in equation 1
x+y = 0
-1 +y =0
Adding +1 on both sides
-1+1+y = 0+1
y = 1
So value of x = -1 and value of y = 1
Solution Set (-1,1)
We would plot the values of x= -1 and y = 1 on the graph.
Graph is attached in the figure below.

Hello Lyn,
To find the discount, you simply have to multiply the percent by the total amount. However, don't forget to convert 20% to the decimal 0.2.
The correct answer is 0.2 x 15 = 3
The discount is $3.
I hope this helps, Good luck!

n=9
Step-by-step explanation:
6^10 = 60466176
6^-4 0.00077160493
60466176 x 0.00077160493 = 46655.9994998
, which is the numerator
6^-5 = 0.00012860082
6^2 = 36
0.00012860082 x 36 = 0.00462962952
46655.9994998 / 0.00462962952 = 10077696
6^9 = 10077696
Therefore, n=9
