How to solve 6y & # 178; - 19y + 10

How to solve 6y & # 178; - 19y + 10

(3y-2)*(2y-5)=0
Y = 2 / 3 or y = 5 / 2

What is the graph represented by equation y & # 178; + 6x-6y + 15 = 0?

y²+6x-6y+15=0
（y-3）²=-6(x+1)
The figure represented by the equation is: parabola

If we know that M is an integer and the graph of the first-order function y = (M + 4) x + m + 2 is only the second quadrant, then M=______ ．

∵ if the graph of a function y = (M + 4) x + m + 2 is only in the second quadrant, ∵ m + 4 ＞ 0m + 2 ≤ 0, the solution is - 4 ＜ m ≤ - 2, and M is an integer, then M = - 3 or - 2

Half, 1, 1, 3, 3 / 2, 5, 2, 7, 5 / 2, 9 what's the rule

It can be divided into two series, that is to say, one after the other
Odd numbers: 1 / 2, 2 / 2, 3 / 2, 4 / 2, 5 / 2, here are 6 / 2 = 3, 7 / 2, 4, 9 / 2
Even numbers: 1, 3, 5, 7, 9. Here are 11, 13, 15

3 / 5 + 2 / 9 + 1 / 5 △ 1 / 2 = [] [process, simple calculation] mathematics

3/5+2/9+1/5 ÷1/2
=3/5+2/9+1/5×2
=3/5+2/9+2/5
=3/5+2/5+2/9
=1+2/9
=1 and 2 / 9

The formula calculates that three-quarters of a number is 12 more than 60, and finds that two-thirds of a number is equal to one-half of four fifths of a number?
The autumn track and field meeting was held. A, B and C ran a relay race. A ran a quarter of the whole race, B ran 70 meters, and C ran two fifths of the whole race. How many meters was the whole race?
For a fraction, the difference between the denominator and the numerator is 9, which is about four out of seven. This fraction used to be ()

Three quarters of a number is 12 more than 60. Find the number (60 + 12) △ 3 / 4 = 72 △ 3 / 4 = 96. Two thirds of a number is equal to one-half of four fifths. This number is? 4 / 5 × 1 / 2 △ 2 / 3 = 2 / 5 △ 2 / 3 = 3 / 5. The autumn track and field sports meeting was held. A, B, C three person relay race was held. A ran a quarter of the whole course, B followed

17 / 18 × 1 and 3 / 8 - 7 / 18 × 3 / 8 [simple calculation]

=Seventeen eighths * (one and three eighths - three eighths)
=17 / 18 * 1
=17 out of 18

How much is eight out of seventeen times nine out of nineteen plus eight out of nineteen times ten out of seventeen,

8 / 17 × 9 / 19 + 8 / 19 × 10 / 17 = 9 / 17 × 8 / 19 + 8 / 19 × 10 / 17 = 8 / 19 × (9 / 17 + 10 / 17) = 8 / 19 × 19 / 17 = 8 / 17, equal to 8 / 17

Simple calculation: 13.1 * 1 / 3-1 / 3 * 1 / 10-1

13.1 * 1 / 3-1 / 3 * 1 / 10-1
=1/3x(13.1-0.1)
=1/3x13
=13/3
