One single choice solution, a few simple multiple choice questions, to find the solution

First, clarify the meaning of k and b.

The first one is oblique truncating, where k represents the slope and b represents the longitudinal intercept.

The second is the intercept type, where k represents the cross section and b represents the longitudinal intercept.

It is found that b has the same meaning, so the two lines should intersect on the y-axis (0,b).

BC is also excluded

The common denominator in AD is that li is monotonically increasing, that is, k 0 so the cross-section of l2 is greater than 0, so d is chosen

Hope to give you a correct answer!

Good luck with your studies!

If l1 and k are positive and b is negative, then the slope of l2 should be positive and wrong;

The main thing is to look at the slope and intercept;

Here the two formulas are not the same, they cannot be directly compared, they can be simplified into the same form, and it is obvious when you look at it again;

For example, they are all in the form of y=kx+b.

If you have any questions, please ask

When x=0, both lines have y=b, so they intersect at (0,b) when b>0, l1 slope: k1=k; L2 slope: k2=-b k They are inverted.

When b<0, the slope of l1: k1=k; L2 slope: k2=-b k They have the same sign. Pick D

l2: y=-bx k+b, when x=0, both straight lines y are equal to b, so the answer is in a and d, when b is negative, l1 and l2 should be both increasing or decreasing functions, there is no in the answer, so b must be greater than 0, and the answer is d

Reason for choosing C: Who is the subject in the sentence, you can't slide and use Whom and don't choose A

If you think the subordinate clause brother has a question word, the question word should be in advance, so choose the letter to stare at C

b Who do you think is the tallest in our class?

According to general usage.

Answer Cdo you think is an insertion, and of course who is used to ask questions about the subject

It must be c, who is at the top.

6 is missing the subject, and countries is n

7 The boy was tall enough for his age I was shorter than him at his age.8 The i was omitted'm waiting for

9 Find here translates as the belief that when used in conjunction with how, there are often 10with adverbials at the beginning of the sentence, followed by doing

(1) The mortgage contract between A and Bank A is valid.

Because the land is mortgaged, the real estate above must be mortgaged together.

2 A This is definitely the right to use.

3 d The accident of the unqualified product of the producer is an infringement.

The merchant is in breach of contract.

4 c The former's liability is mainly in the form of damages, while the latter's is mainly in the form of repair and replacement.

If the calculation is increased by 5%, it will be 1 ten 5% = 105%, and the actual increase of 10% will be 1 ten 10% = 110%, and the excess part is (110% - 105%) 1o5% = 5% 105% = =

Plan B increases by 5%, 100 (1+5%) 105

Actual increase of 10%, 100 (1 10%) 110

Actual Enhancement Planned Enhancement 110 105

The first thing to do is to understand the meaning of each option.

A yes, sooner or later.

B is, occasionally.

C is, to be precise.

Believe it or not.

From these two sentences, the second person agrees with what the first person says, so A and B can be excluded.

But C is too absolute.

So to choose d, I use the method of elimination.

Hope it helps.

Pick DAnalysis:

or later sooner or later.

in a while occasionally, occasionally.

The EAXCT to be precise.

it or not, believe it or not.
