Answer:
$5,172.93
Step-by-step explanation:
We're gonna use the simple interest formula: P = A(1 + r(t))
P = final amount
A = starting amount (4,678)
r = rate (0.073)
t = years (529/365)
P = 4,678(1 + 0.073(529/365))
P = 5,172.9324
So there are two ways.
First you could solve for y and plug it into the calculator. one equation for y1 and another for y2. Then go 2nd trace and press 5 and then press enter 3 times to find the intersection.
the second way is to solve by hand. I would suggest solve the first equation for y and plug the equation solved for y into the other equation. so y = -3x + 9 and 3x-5y=15. Then you could do 3x - 5(-3x+9) = 15. Finally solve for x and plug in x into both equations to see if you get the same y value.
The answer should be (10/3, -1)
Answer:
- ∞ < x < ∞
Step-by-step explanation:
The domain of a quadratic function is all real values of x , that is
