Let x represent the amount of money he invested at 11% and y money he invested at 12%. Now we write system of equations:
x*1.11 + y*1.12 = 70 000 + 7900
x + y = 70 000
We will multiply second equation with 1.11
x*1.11 + y*1.11 = 77700
and subtract if from first:
0.01*y = 200
y = 20000
x = 70000 - 20000 = 50000
Answer:
The answer is D (The graph increases, then decreases.)
Step-by-step explanation:
Because it is
So, <span>y = 4^x is the same thing as the [inverse log] of 4^x. X is going to be left allow, which means bring it down and the log of is 4. So, y would be the inverse log of X log of 4.</span>
