F(x) = 2|x| + 3x
f(1) = 2|1| + 3(1)
f(1) = 2 + 3
f(1) = 5
<span>The slope of the line is equal to (y - 7) / (x - 4)
Then we can set up this equation:
(y - 7) / (x - 4) = 3
y - 7 = 3 * (x - 4)
y - 7 = 3x - 12
y = 3x - 5
This is the equation of the line.</span>
We are given
P = $754.43
r = 13.6% annual
for a.
A = 150
for b.
A = 300
First, change the interest into effective monthly
i = (1 + 0.136/12)^12 - 1
Solve for i
Next, use the general formula
A = P i ( 1 + i)^n / (1 + 1)^n - 1
Subsitute P, i, and A for a and b.
Then, solve for n for a and b.
Answer:
Quarters: 2 = 50 cents. 50cents
Dimes: 2 = 20 cents. 70cents
Nickels: 8 = 40 cents. $1.10
