Answer:

Flip the inequality sign!

Step-by-step explanation:

There is one very important exception to the rule that multiplying or dividing an inequality is the same as multiplying or dividing an equation. Whenever you multiply or divide an inequality by a negative number, you must flip the inequality sign.

Answe 25 and 26 easy
Zina [86]

Answer:

25. rational

26. irrational

Step-by-step explanation:

A rational number is a number that can be written as a fraction. It may have decimals that end or repeating decimals.

An irrational number cannot be written as a fraction. It's decimals continue on and do not repeat.

25.

When you multiply two rational numbers, the product is rational. The square root of 16 is 4, which is rational because it is a whole number. 4/7 is written as a fraction so it is rational.

26.

The square root of 2 is an irrational number because its decimals go on and do not repeat. 7 is a whole number so it is rational. Subtracting a irrational number from a rational number gives an irrational number.

Minimize the objective function P = 45x + 48y for the given constraints.
BabaBlast [244]

Answer:

Following are the solution to the given equation:

Step-by-step explanation:

The graph file and correct question are defined in the attachment please find it.

According to the linear programming principle, we predict, that towards the intersections of the constraint points in the viability area, and its optimal solution exists.  The sketch shows the points that are (0,16), (3,1), and (6,0).

by putting each point value into the objective function:

\to P(0,16) = 768\\\\\to P(3,1) = 183\\\\\to P(6,0) = 270

Thus, the objective of the function is reduced with a value of 183 at (3,1).
