Answer:
The solution is going to be the point where the two lines on a graph intersect.
Step-by-step explanation:
The solution of a system is going to be a ordered pair that satisfies all of the equations in the system. This translates to the lines intersecting on a graph since they all go through the same ordered pair.

Answer:
mark=$2400 &Saul=$4800
Step-by-step explanation:
For mark:
p=$12000
r=4%
t=5 years
I=prt/100
12000*4*5/100= 2400
For Saul:
p=$10000
r=6%
t=8 years
SI=prt/100
10000*6*8/100= 4800
Answer:
Domain: -4 < x < 4
Zeros: (-2, 0), (0, 0) and (2, 0)
The function is positive if: 0 < x < 2
The function is negative if: -4 < x < 0 and 2 < x < 4
Step-by-step explanation:
Domain of the function are those x values where the function is defined, For this case, -4 < x < 4
Zeros of a function are those x values where y = 0, that is, the graph intersect x-axis. For this case, the points are: (-2, 0), (0, 0) and (2, 0)
The function is positive if the graph o the function is above x-axis. For this case, the function is positive at the interval (0, 2)
The function is negative if the graph o the function is below x-axis. For this case, the function is negative at the intervals (-4, 0) and (2, 4)
