Based off of your question, I'll assume you are trying to solve for the "y" variable.
To solve the variable, we need to isolate it by performing opposite operations. However, it's important to remember to perform the operations on both sides of the equal sign so that the equation remains equal
.-6y-3=3-6y
+3+3
-6y=6-6y
/-6 /-6
y=6+1y
y=y+6
In this case, it looks like we actually have a bit of an odd circumstance. We know that "y" cannot equal "y+ a value," because it simply does not logically make sense.
Therefore, using that logic, we can determine that this equation has no solutions.

Answer:
The third answer (C).
Step-by-step explanation:
This graph starts at 10. So it needs the +10 at the end.
Also the slope is -1/2 because the graph goes down one, right two. Rise/run.
For the first one, it's (a^8b^6). For the second one, it's 81m^8n^20.
Answer:
Any expression that has an X with an exponent of 4 and no other higher exponent.
Step-by-step explanation:
The degree of an expression is the highest exponent on an X in the equation.
Answer: $7800 was invested at 9%
$5900 was invested at 3%
Step-by-step explanation:
Let x represent the amount invested in the fund that paid a dividend of 9%.
Let y represent the amount invested in the fund that paid a dividend of 3%.
Last year, the first fund paid a dividend of 9% and the second a dividend of 3%, and you received a total of $879. This means that
0.09x + 0.03y = 879- - - - - - - - - 1
This year, the first fund paid a 10% dividend and the second only 1%, and you received a total of $839. It means that
0.1x + 0.01y = 839 - - - - - - - - - -2
Multiplying equation 1 by 0.1 and equation 2 by 0.09, it becomes
0.009x + 0.003y = 87.9
0.009x + 0.0009y = 75.51
Subtracting, it becomes
0.0021y = 12.39
y = 12.39/0.0021
y = 5900
Substituting y = 5900 into equation 1, it becomes
0.09x + 0.03 × 5900 = 879
0.09x + 177 = 879
0.09x = 879 - 177
0.09x = 702
x = 702/0.09
x = 7800
