Select all the correct answers. steve's doctor has advised him to take protein supplements. he bought two brands, brand a and brand b. the table gives the amount of calcium, iron, and vitamins (in milligrams per spoonful) in each of the two brands. brand calcium iron vitamins a 5 4 7 b 4 6 4 steve needs to take at least 24 milligrams of calcium, 15 milligrams of iron, and 16 milligrams of vitamins. which ordered pairs of values are solutions for the given system inequalities, where x represents the number of spoonfuls of brand a that steve takes and y represents the number of spoonfuls of brand b that steve takes? select all the correct answers. (1, 4) (1, 5) (2, 3) (3, 2) (4, 1)

The three inequalities are ...

A graph is useful for this. Satisfying the constraint on calcium will satisfy the other constraints. Correct choices include (1, 5), (4, 1).

The correct options are 2 and 5.

Step-by-step explanation:

The given table is

Brand            A             B

Calcium         5             4

Iron                4             6

Vitamins        7             4

Let, x represents the number of spoonfuls of brand A that Steve takes and y represents the number of spoonfuls of brand B that Steve takes.

It is given that Steve needs to take at least 24 milligrams of calcium, 15 milligrams of iron, and 16 milligrams of vitamins.

The points are (1, 4),(1, 5), (2, 3), (3, 2), (4, 1).

Check the above inequalities by each point.

All the above inequality satisfy by points (1,5) and (4,1), because (1,5) and (4,1) lie in the feasible region.

Check the inequalities for (1,5).

All the statements are true.

Check the inequalities for (4,1).

All the statements are true.

Therefore the correct options are 2 and 5.
