D is your answer if you times 8 and 2 together to get your A& B
I=prt
I interest earned
P principle 4000
R interest rate 0.095
T time270/365
I=4,000×0.095×(270÷365)
I=281.10
X³ = -1000
x = ∛-1000
x = -10
In short, Your Answer would be: -10
Hope this helps!
C. Negative because since the neutral atom stands at 0 and positive ions are 1+ and electrons are negative if it gains the electron ( negative ) it will become negative.
If we have
y = 6x + 1 and x - y = 11, we can take advantage of y - y = 0 as follows:
Subtract x from both sides of the 2nd equation:
-y = 11 - x
Now combine
y = 6x + 1
-y = 11 - x
--------------
0 = 5x + 12. Solving for x, x = -12/5. Using the equation above, find y:
-y = 11 - x
= 11 - (-12/5)
= 55/5 + 12/5 = 67/5
Then the solution is (-12.5, 67/5).
