It said so.
Answer:

Step-by-step explanation:
Given
-- Rate
-- Principal
-- Time
Required
Determine the compound interest
First, we calculate the Amount (A)


Express % as decimal



The compound interest (C) is then calculated as:
i.e. Amount - Principal


The x is going to be a negative number to get the 3. so start off minus 5 from plus 5 and minus five from the other side too. the positive 5 and the negative cancel out and then take it fromt here with three and the negative 5.
Part (a)
<h3>Answer: y1 and y3 are perpendicular</h3>
This is because the two slopes 2 and -1/2 multiply to -1. Perpendicular slopes multiply to -1 assuming neither line is vertical or horizontal.
=====================================================
Part (b)
Graph each line to see where they cross. The three points of intersection are
(0,4)
(2,-2)
(4,2)
The order of the points doesn't matter.
You could also form three systems of equations pairing up the equations, and solving each system. That way you can find the points of intersection. Graphing may be a better and faster route in my opinion. See the diagram below.
I know the correct answers but I need you to answer my math questions first
