Answer:
x = - 9 (negative 9)
Step-by-step explanation:
The x intercept is where y = 0. When y = 0, the point is on the x axis.
So use the equation and replace y with 0.
-2x + 1/2y = 18
-2x + 1/2(0) = 18
-2x + 0 = 18
-2x = 18
x = - 9
Check you answer by putting your answer for x into the equation. See if it does make y = 0
-2x + 1/2y = 18
-2(- 9) + 1/2y = 18
18 + 1/2y = 18
1/2y = 0 so y must also equal 0
Answer:
a) About 12%
Step-by-step explanation:
We need to find the interest rate required to achieve her goal, so we will need to use the interest-compound formula:
Where:
PV= Present Value
i= interest rate
FV= Future Value
n= number of periods
replacing the data provided:
solving for i:
first, divide both sides by 50.000 to simplify the equation:
Take 
roots of both sides:
±![\sqrt[10]{3}](https://tex.z-dn.net/?f=%5Csqrt%5B10%5D%7B3%7D)
solve for i:
±![\sqrt[10]{3} -1](https://tex.z-dn.net/?f=%5Csqrt%5B10%5D%7B3%7D%20-1)
We get two answers, but we look for a coherent value. So we take the positive one:
≈12
