Answer: First Option is correct.
Step-by-step explanation:
Since we have given that
Now, we will use "Substitution Method" to find the values of x and y:
Put the value of x in first equation i.e.
Now, we use the value of y in equation (3),
Hence, values of (x,y) is (4,1).
Therefore, First Option is correct.
10,000,000+2,000,000+400,000+30,000
For, f(1) = 2-3x =2-3 =-1
and, for, g(1) = | 2-3x | =| -1 | = 1 (The symbol | | determines the abstract value i.e, positive value)
Answer:
140 markers
Step-by-step explanation:
From the question;
- The teacher bought 5 boxes of markers
- Markers in 1 box = 28 markers

Therefore;
Number of markers bought = 5 boxes × 28 markers/box
= 140 markers
Thus, the teacher bought 140 markers
