Please help me with the questions

The answer is no solution.

48a is greater than or equal to a+b+c+d....the sum of i;

48b is greater than or equal to 2 times (a+b+c+d...).the sum of i;

48C is greater than or equal to 4 times (A+B+C+D...).the sum of i;

48d is greater than or equal to 3 times (a+b+c+d...).the sum of i;

48e is greater than or equal to 6 times (a+b+c+d...).the sum of i;

48f is greater than or equal to 12 times (a+b+c+d...).the sum of i;

48g is greater than or equal to 4 times (a+b+c+d...).the sum of i;

48h is greater than or equal to 8 times (a+b+c+d...).the sum of i;

48i is greater than or equal to 16 times (a+b+c+d...)the sum of i;

There is no solution to the programming.

This problem seems to be unsolvable.

There should be no ...... solution to this problemAccording to the title:

48a is greater than or equal to a+b+c+d....the sum of i;

48b is greater than or equal to 2 times (a+b+c+d...).the sum of i;

48C is greater than or equal to 4 times (A+B+C+D...).the sum of i;

48d is greater than or equal to 3 times (a+b+c+d...).the sum of i;

48e is greater than or equal to 6 times (a+b+c+d...).the sum of i;

48f is greater than or equal to 12 times (a+b+c+d...).the sum of i;

48g is greater than or equal to 4 times (a+b+c+d...).the sum of i;

48h is greater than or equal to 8 times (a+b+c+d...).the sum of i;

48i is greater than or equal to 16 times (a+b+c+d...)the sum of i;

Then the above equation adds up: 48 times (a+b+c+d...).i) is greater than or equal to 1 + 2 + 4 + 3 + 6 + 12 + 4 + 8 + 16 = 56 times (a + b + c + d...).the sum of i;

...... contradictory to the titleSo ......Did you make a mistake in the question?

I don't understand, what is this? I won't do it, be honest! Give me a reward for honesty!

It's not something we have to learn if we don't know how to pretend to understand. 886

It's equal to one less person.

So it's a common multiple of 3 5 7 9 11 minus 1

5*7*9*11-1 3465-1 3464 people.

In order to let the landlord see the idea clearly, let's make an image of my answer. In fact, if you think about it carefully, there should be more than 18 words (e.g., Wu, Yuan......）

If the image is too small, click ** to enlarge it.

Standing up in the morning of the day, the sound of the early chapter, the ten ancient brothers, the brother Ke actually competed for the first two grasses.

One, six, stand, early, chapter, day, ten, brother, mouth, son, sound, gram, ancient, actually.

First of all, there are four basics, the ten brothers of Liri.

There are 18 in total, which can be disassembled and combined.

One, two, three, ten, mouth, ancient, brother, son, gram).

Satisfied!

1。If the dog catches up with the rabbit, it will take x seconds to run. 150+7x=9x，2x=150，x=75

2.== I'm a little dizzy with this kind of question.

The rabbit is 150 feet in front of the dog and runs 7 feet per second, the dog chases the rabbit in the same direction behind, the dog runs 9 feet per second, and the dog runs 75 seconds to catch up with the rabbit.

'(x)=3x 2-2ax-3 0 is constant at x 1,+.

a [3x 2 -3 (2x)] is constant at x 1,+.

i.e. a [3x 2 -3 (2x)] minimum value on x 1,+ 0, a 0

2.x 3-ax 2-3x=(a 2-3)x-1(a>0) has at most two solutions.

That is, h(x)=x3-ax 2-a2 x+1 has two intersections with the x-axis at a>0.

by h'(x)=3x 2-2ax-a 2=(x-a)(3x+a) (a>0)Know:

h(x) in (- a 3) single increase, in (-a 3, a) single decrease, in (a,+ single increase, and x tends to -, h(x)<0, h(0)=1>0, to meet the meaning of the question only h(a) 0,0 glad to answer for you, I wish you progress in learning! The [the1900] team will answer the questions for you.

f(x)=(a 2-3)x-1 (a>0) is a straight line that passes through a fixed point (0,-1).

If there are at most two solutions, it means that there are at most two points, and two points are impossible, so there is only one point (0, -1), so a 2-3≠0, and because a > 0, so: the value range of the real number a: a>0, and a ≠ 3

I wish you progress in your studies and go to the next level! (

Dude, this is not an equation, you give me a function, how do I know which solution you want. Is it (a 2-3) x-1 = 0 (a > 0).

A one-time function? Is there a mistake in the question?
