The solutions to the system of equations is 
Explanation:
Given the system of equations are
and 
We need to determine the solution to the system of equations.
Let us plot the equation
in the graph.
When
, we get, 
When
, we get, 
Thus, the coordinates are (0,6) and (3,0)
Let us plot the equation
in the graph.
When
, we get, 
When
, we get, 
Thus, the coordinates are (0,-7) and (5,0)
The solution to the system of equations is the point of intersection of the two lines.
Thus, the lines intersect at the point 
The approximate values of the point is 
Thus, the solution is 
A) 100 • 3 • x
b) 100 + 2100 = 2,200 in one week
c) 300 • 30 = 9,000 + 100 = 9,100 in a month with 30 days
Answer:
d = 16
Step-by-step explanation:
15 = d-1
Add 1 to each side
15 +1 =d-1+1
16 =d
