If the distance between the image of the linear function y = KX + 3 and the two intersections of the coordinate axis is 5, then the value of K is 0______ ．
Let x = 0 and y = 3 in y = KX + 3, then the intersection coordinates of function and Y axis are: (0, 3); let the intersection coordinates of function and X axis be (a, 0), according to Pythagorean theorem, A2 + 32 = 25 and a = ± 4; when a = 4, substitute (4, 0) into y = KX + 3 and K = - 34; when a = - 4, substitute (- 4, 0) into y = KX + 3 and K = 34
Multiply a number by 6, subtract 6, and then divide by 6. The result is still 6
(6 × 6 + 6) △ 6 = (36 + 6) △ 6, = 42 △ 6, = 7
Let f (x) = Log1 / 2 (1-ax) / (x-1) be an odd function, and a be a constant. Can the great gods of finding the value of a be 1 help
There's something wrong with the expression. That's true
How to calculate 100.4-9 + 0.77/1.1
Let's first explain if we can simplify the calculation
100.4-9+0.77/1.1
=100.4-9+0.7
=91.4+0.7
=92.1
m. N is reciprocal to each other, X and y are opposite to each other, and the absolute value of a is 4
m. N is reciprocal to each other, -- > Mn = 1
x. Y is opposite to each other, -- > x + y = 0
The absolute value of a is 4, -- > A = 4 or - 4
（1）a=4:
Original formula = (0 / 1) ^ 2-16 + 4 = - 12
(2) A = - 4: original formula = 0-16-4 = - 20

Expand the determinant according to the third column and calculate its value: the first row 10 a 1, the second row 0 - 1 B - 1, the third row - 1 - 1 C - 1, the fourth row - 1 d 0
Please see the following:
105 divided by 7 divided by 3
105÷7÷3
=105 ÷ (7X3) (division rule)
=105÷21
=5
Well, I hope to adopt the original answer (if you have the same answer as me, please see the submission time)
