Answer:
1/10 in first row
1/20 in second row
1/5 in third row
Step-by-step explanation:
it is simple, take first row, and look what is required to get 1,
here 5*2 is 10, so to get 1 we need to divide with 10
in second row, 20*1 is 20, so we need to divide with 20
and in third row 10* ½ is 5, so we need to divide with 5
In matrix form, this is
The coefficient matrix has determinant
so it has an inverse, which is
Multiply both sides by the inverse matrix:
so that 
and

Ms. Cassidy instructed Miguel to change one sign of the graph of y < 2x – 4 so that point (2, 3) can be included in the solution set.
To check which of the given options might Miguel write we check the inequality that holds true for the point (2,3).Substituting x=2 ,y=3 we have:
1) y < 2x – 1
3<2(2)-1
3<3 Not True.
2)y ≤ 2x – 4
3≤ 2(2) -4
3≤ 0 .Not true.
3) y > 2x – 4
3> 2(2)-4
3> 0 True.
4) y < 2x + 4
3<2(2)+4
3<8 True
5) .y < 3.5x – 4
3< 3.5(2)-4
3<3 Not true
6) y < 4x – 4
3<4(2)-4
3<4 True.
Options 3 ,4 ,6 holds true for the point (2,3)
