The correct answer is B) y + 9 = 2(x - 1)
In order to find this, simply take the point and the slope and plug into the base form of point-slope form.
y - y1 = m(x - x1)
Use the slope for m and the point for (x1, y1)
y + 9 = 2(x - 1)
Answer:
7.87 years
Step-by-step explanation:
#First we determine the effective annual rate based on the 9% compounded semi annual;

#We then use this effective rate in the compound interest formula to solve for n. Given that the principal doubles after 2 yrs:

Hence, it takes 7.87 years for the principal amount to double.

i can give give u a website that does this, if u want
1. x=1
5x=4+x
4x=4
x=1
2. x=3/4 or 0.75
2/3x=1/2
2x=1 1/2
x=3/4
3. x=1
3x-2x+4=15/3
x+4=15/3
x=1
4. x=5
4x+7=2x+17
2x+7=17
2x=10
x=5
5. x=20
.5x=10
x=20
