Answer:
The coordinates of the vertex are (7,-3)
Step-by-step explanation:
To find the coordinate of vertex, since it is at the intersection of the graphs, we shall need to solve both equations simultaneously;
That would be;
2x + 3y = 5
3x + y = 18
From the second equation;
y = 18-3x
We can easily substitute this into the first equation;
We have;
2x + 3(18-3x) = 5
2x + 54 -9x = 5
2x-9x = 5-54
-7x = -49
x = -49/-7
x = 7
Kindly recall;
y = 18-3x = 18-3(7) = 18-21 = -3
So the coordinates of the vertex are (7,-3)
Answer:
The result is the number of years, approximately, it'll take for your money to double. For example, if an investment scheme promises an 8% annual compounded rate of return, it will take approximately nine years (72 / 8 = 9) to double the invested money
I believe you are right I checked the work and everything seems to be good !
