Answer:
Sh. 10,920
Step-by-step explanation:
Since the sales is above sh. 100,000,his commission is (2.4+1.5) 3.9%.
3.9% of 280,000= 10920.
Therefore, his commission is sh. 10,920
Answer: Yes, the point (3,4) is a solution to the system.
===================================================
Proof of this:
Replace x with 3 and y with 4 in the first equation
x+y = 7
3+4 = 7
7 = 7
This confirms the first equation. Repeat for the second equation
x-2y = -5
3-2(4) = -5
3 - 8 = -5
-5 = -5
We get true equations for both when we plug in (x,y) = (3,4). This confirms it is a valid solution to the system of equations. It turns out it's the only solution to this system of equations. Visually, the two lines cross at the single location (3,4).
Yes -1 is a rational number. We can express it as a fraction of two whole numbers
One way is -1 = -1/1
