#2, Y=8, x=3
because if you subsitute those variables in,
8=3+5
4x3+8=20
Ill show you step by step.
This is what the equation should look like
Y=Initial value(1+/- Increasing or Decreasing value)^2 Which stands for time
So you need to do 1.0525 to the 2nd power Which equals 1.10775625
So now you need to do 15,000(1.10775625)
------------------------------------------------------------------------------------
Which equals <span>16616 rounding to the nearest Ones
16616.3 rounding to the nearest tenth</span>
The way you wrote it could have 2 meanings:
Sum of twice a and 4 could be:
2a+4 or 2(a+4) which will give different results.
In the first case:
2a+4
a= 4/2
a= 2
So the sum would be 2*2+4 = 4+4 = 8
In the second case:
2(a+4) = 2a + 2*4 = 2a + 8
a= 8/2
a=4
2(4+4) = 2*8 = 16
