Responder: Qinglong Breath-ranking11-120: 42.

The maximum value of x is 5, and the maximum value of y is 2.

Responder: Qing Feng A Geng-Trainee Magician Level 2 1 1- 1 20:43.

The combination of numbers and shapes,

Draw curves represented by the following types:

X+2Y-5=0

X= 1

Y=0

X+2Y-3=0

The above four curves form a polygon.

Let K=Y/X, and we can know from the following conditions that the area of polygon is the value range of k.

X+2Y-5≤0

X≥ 1

Y≥0

X+2Y-3≥0

According to the meaning of the question, Y=KX intersects the polygon, that is, the maximum and minimum values of slope k are found.

Interviewee: immigrant fairy-assistant level 3 1 1- 1 20:48

3 ≤ X+2Y ≤5 requires the maximum value, and requires that Y be as large as possible and X be as small as possible.

Therefore, the minimum x is 1, the maximum y is 2, and the maximum Y/X is 2.

Because Y/X must be greater than or equal to 0, and y can take 0. The minimum value is 0.

Answer will get 2 points, if the answer is accepted, you will get bonus points and 20 points. Integral rule

Solution: 3 ≤ X+2Y ≤5 requires the maximum value, and requires that Y be as large as possible and X be as small as possible.

Therefore, the minimum x is 1, the maximum y is 2, and the maximum Y/X is 2.

Because Y/X must be greater than or equal to 0, and y can take 0. The minimum value is 0.

First of all, y can take 0, but when y takes 0, x has to take 3.

Similarly, the minimum value of x can also be 1 and y is 2.

It is much easier to think in a logical way.

3 is less than X+2Y is less than 5, x is greater than or equal to 1, and y is greater than or equal to 0.

There is a question to know:

Y=0 is the minimum value and X=5 is the maximum value.

X= 1 is the minimum value and Y=2 is the maximum value.

So:

The maximum x is 5 and the minimum x is 1.

The maximum value of y is 2 and the minimum value is 0.

Respondent: Yu Ran-doorman II11-121:30.

Respondent: Sun Chao-Assistant Level 31-122: 50.

Hello, little brother. Because both x and y are numbers greater than 0, Y/X has a minimum value of 0 only when y takes 0. When x adopts the minimum tangent and y adopts the maximum tangent, the maximum tangent of Y/X is 2.

Respondent: Double Assistant Level 2 1 1- 1 23:06.

When the minimum value of x is 1, the maximum value of y is 2 and the minimum value of y is 1.

When the maximum value of X is 5, the maximum value of Y is 0 and the minimum value of Y is 0.

When y is the minimum value of 0, the maximum value of x is 5 and the minimum value of x is 3.

When y is the maximum value of 2, the maximum value of x is 1 and the minimum value of x is 1.

This is the correct answer.

Respondent: Martial Arts Academy 2003- probationary period level 11-123: 46.

The maximum value of y/x is 2 and the minimum value is 0.

Respondent: Xiao's second assistant 1 1-2 09:04
