Given that in the function y = KX (K ≠ 0), y increases with the increase of X, then the image of a function y = kx-k passes () A. One, two, three quadrants B. one, two, four quadrants C. one, three, four quadrants D. two, three, four quadrants

Given that in the function y = KX (K ≠ 0), y increases with the increase of X, then the image of a function y = kx-k passes () A. One, two, three quadrants B. one, two, four quadrants C. one, three, four quadrants D. two, three, four quadrants

It is known that: k > 0, then in the linear function y = kx-k, it is equivalent to: k > 0, B < 0, that is, the image passes through the first, third and fourth quadrants

If an image with positive scale function y = 2x and inverse scale function y = K / X (k is not equal to 0) has an intersection coordinate of (2,4), then its other intersection coordinate is?
A.(2,-4) B.(-2,4) C.(-2,-4) D.(-2,-2)

The answer is c algorithm has two kinds: 1, smart algorithm (substitution method) because since it is the intersection point, then the coordinates of this point must be suitable for the two equations, so the four points are substituted into y = 2x, only C is suitable for the equation, so C is the correct answer. 2, honest algorithm (hard work method) 1, find the value of K, and (2,4) into y

If the solution set of inequality system {X-2} is greater than or equal to a {x + 2} and greater than 3a is an empty set, then what is the value range of a

x-2>=a x>=a+2
x+2>3a x

Is each followed by plural or singular? Is each of followed by singular or plural?

Like both, each is only used before the plural and can be followed by of + these / those. Pronouns after of are only used in the plural

Let a = (2,1), B = (4,4) C = (- 3,2), then (a-2c)=

Is it (a-2c) x B?
The result was 20
Multiply the abscissa and ordinate of C by 2, and then subtract the abscissa and ordinate of 2C from the abscissa and ordinate of A
And then we get the coordinates and the coordinates of B, the abscissa times the abscissa plus the ordinate times the ordinate

D. E is respectively on AB and AC of triangle ABC, BD = CE, M. n is respectively be, CD, the reverse extension of midpoint and Mn is respectively AB, AC and point P, O, and AP = aq
Draw your own picture

If the midpoint of BC is f, connecting MF and NF, it is easy to prove that MF = NF, then the angle FMN = FNM. According to the equality of internal stagger angles, it is easy to prove that the angle FMN = AQP, Apq = FNM, and so on

Are collective nouns singular or plural?

This kind of noun is plural in meaning, but singular in grammatical form. When this kind of noun is used as subject, it follows the two principles of "grammatical consistency" and "meaning consistency"

In an equilateral triangle, point E is on line AB, point D is on line BC, and ED = EC. If the side length of triangle ABC is 2, AE = 4, find the length of CD

From the known information, we can know that point e should be on the extension line of ab. through point E, we can make the vertical line of edge BC, and the perpendicular foot is point F. from the known, we can get CF = DF, CD = CF + DF. In RT △ EBF, there is ∠ B = 60, BF = (Ba + AE) / 2 = (2 + 4) / 2 = 3, because BF = BC + CF, so
