A. [tex]\((1,6)\)[/tex]

B. [tex]\((-6,0)\)[/tex]

C. [tex]\((0,5)\)[/tex]

D. [tex]\((5,0)\)[/tex]



Answer :

To determine which of the given points is a solution to the system of inequalities

[tex]\[ \begin{array}{l} y \leq 2x + 2 \\ y \geq -5x + 4 \end{array} \][/tex]

we will evaluate each point against both inequalities to check if it satisfies them.

Let's analyze each point one by one:

### Point A: [tex]\((1, 6)\)[/tex]
1. For [tex]\( y \leq 2x + 2 \)[/tex]:
[tex]\[ y = 6\quad \leq \quad 2(1) + 2 = 4 \][/tex]
This is false, since [tex]\(6 \leq 4\)[/tex] is not true.

Since one of the inequalities is not satisfied, point [tex]\((1, 6)\)[/tex] is not a solution.

### Point B: [tex]\((-6, 0)\)[/tex]
1. For [tex]\( y \leq 2x + 2 \)[/tex]:
[tex]\[ y = 0\quad \leq \quad 2(-6) + 2 = -12 + 2 = -10 \][/tex]
This is false, since [tex]\(0 \leq -10\)[/tex] is not true.

Again, since one of the inequalities is not satisfied, point [tex]\((-6, 0)\)[/tex] is not a solution.

### Point C: [tex]\((0, 5)\)[/tex]
1. For [tex]\( y \leq 2x + 2 \)[/tex]:
[tex]\[ y = 5\quad \leq \quad 2(0) + 2 = 2 \][/tex]
This is false, since [tex]\(5 \leq 2\)[/tex] is not true.

Since one of the inequalities is not satisfied, point [tex]\((0, 5)\)[/tex] is not a solution.

### Point D: [tex]\((5, 0)\)[/tex]
1. For [tex]\( y \leq 2x + 2 \)[/tex]:
[tex]\[ y = 0\quad \leq \quad 2(5) + 2 = 10 + 2 = 12 \][/tex]
This is true, since [tex]\(0 \leq 12\)[/tex].

2. For [tex]\( y \geq -5x + 4 \)[/tex]:
[tex]\[ y = 0\quad \geq \quad -5(5) + 4 = -25 + 4 = -21 \][/tex]
This is also true, since [tex]\(0 \geq -21\)[/tex].

Since point [tex]\((5, 0)\)[/tex] satisfies both inequalities, it is a solution.

### Conclusion

Therefore, the point that is a solution to the system of inequalities is:
[tex]\[ \boxed{(5, 0)} \][/tex]
