Answer:
$872
Step-by-step explanation:
Simple interest = Principle * Rate * Time / 100
= ( 800 * 6 * 18/12 ) / 100
= $ 72
The balance after 18 months = principle + interest
= 800 + 72
= $ 872
The y-intercept on the x-y plane is (0, -9).
<h3 /><h3>How to get the y-intercept?</h3>
To get the y-intercept we just need to evaluate in x = 0.
Here we have:
y = 6*(x - 1/2)*(x + 3)
Evaluating the given equation in x = 0 we get:
y = 6*(0 - 1/2)*(0 + 3) = -9
Then the y-intercept on the x-y plane is (0, -9).

12*3^2+36 needs to be 540
12*9+36
9+36=45
12*45=540 so
12(3^2+36)
11.
32/2^3-4 needs to be 8
32/(2^3-4)
12.
2.3^2+9*4/2 needs to be 28.58
5.29+9*4/2
(5.29+9)*4/2=28.58
(2.3^2+9)*4/2
Hope this helps :)
