Answer:

Minimum = 0

Maximum = 15

Step-by-step explanation:

Given

Optimization Equation: z = 2x + 5y

Constraints:

2x- y \le 12

4x + 2y \ge 0

x + 2y \le 6

x,y\ge 0

Required

The maximum and the minimum values of z

To do this, we make use of graphical method.

Plot the constraints on a graph (see attachment)

Get the corner points from the points.

These are the points where x,y\ge 0

So, we have:

(x_1,y_1) = (0,0)

(x_2,y_2) = (0,3)

(x_3,y_3) = (6,0)

Substitute these points in the optimization equation:

(x_1,y_1) = (0,0)

z = 2x + 5y

z = 2 * 0 + 5 * 0 = 0

(x_2,y_2) = (0,3)

z = 2 * 0 + 5 * 3 = 15

(x_3,y_3) = (6,0)

z = 2 * 6 + 5 * 0 = 12

So, the values are:

Minimum = 0

Maximum = 15

The reflexive property of congruence allows you to say that RST=____
weqwewe [10]

Answer:

The reflexive property of congruence allow us to say that RST = RST .

Option (C) is correct .

Step-by-step explanation:

Definition of Reflexive Property of congurence

The meaning of  Congruence is  figure has the same size and shape. If you were comparing something to itself, then it definitely have the same size and shape this is called Reflexive Property of congurence .

By using Reflexive property of congurence .

RST = RST

Therefore reflexive property of congruence allow us to say  that RST = RST .

Option (C) is correct .

I need help with dividing fractions
iVinArrow [24]

When you divide fractions, you want to use keep change flip.

You keep the 1st fraction, change the division sign into a multiplication sign, then flip the last fraction.

Let’s use 3/4 ÷ 2/3

Keep 3/4 the same, change the division sign into a multiplication sign, and flip 2/3 so that it is 3/2

It’ll look like this

3/4 x 3/2

Now just multiply the numerators, 2 x 3, then multiply the demoninators, 4 x 2.

You get 6/8

Simplify this number and you get 3/4.

If you have any further questions feel free to ask.

Hope this helps.
