if you’re good with set theory and this sudoko puzzle in math 30 please help with question 33!! real answers only !!
Sidana [21]

Answer:  A) 2, 7, 9

<u>Step-by-step explanation:</u>

In a sudoku puzzle, there are three rules:

  1. Each vertical line must contain the numbers 1 - 9, with no duplicates
  2. Each horizontal line must contain the numbers 1 - 9, with no duplicates
  3. Each 3 x 3 box must contain the numbers 1 - 9, with no duplicates.

Using logic:

2 must go in the 1st box. It cannot go in the 2nd or 3rd shaded square because 2 is already in that 3 x 3 box.

That leaves the 2nd and 3rd shaded square.  

9 cannot go in the 2nd shaded square because 9 is already in that vertical line.

Therefore, 9 must go in the 3rd shaded square.

That leaves the 2nd shaded square.

7 must go in the 2nd shaded square because it is the only number remaining (2 and 9 have already been placed in the other squares).

Write he standard form of the equation; Through: (-1,5) and (1,2)
JulsSmile [24]
Standard form is ax+by=c where a,b, and c are integers and a is usually positive

so
first find slope
get into form y=mx+b where m is slope
so
slope between points (x1,y1) and (x2,y2) is
(y2-y1)/(x2-x1)
points (-1,5) and (1,2)
slope is (2-5)/(1-(-1))=-3/(1+1)=-3/2
y=-3/2x+b
find b
sub a point
(1,2)
2=-3/2(1)+b
2=-3/2+b
4/2=-3/2+b
7/2=b

y=-3/2x+7/2
add 3/2 both sides
3/2x+y=7/2
times 2 both sides
3x+2y=7 is standard form
