Answer:

No ordered pair.

Step-by-step explanation:

Given: System of linear inequality

y>x

y<x + 1

We need to find out ordered pair which are solution set of system of linear inequality.

We have to check each one

Option 1: False

Ordered pair       y>x     Conclusion     y<x+1     Conclusion       Solution    

   (5,-2)              -2>5         False          -2<5+1        True                  No

   (3,1)                  1>3         False            1<3+1         True                  No

   (-4,2)              2>-4         True             2<-4+1       False                 No

Option 2: False

Ordered pair       y>x     Conclusion     y<x+1     Conclusion       Solution    

   (5,-2)              -2>5         False          -2<5+1         True                  No

   (3,-1)                -1>3         False           -1<3+1         True                  No

   (4,-3)              -3>4         False           -3<4+1         True                 No

Option 3: False

Ordered pair       y>x     Conclusion     y<x+1     Conclusion       Solution    

   (5,-2)              -2>5         False          -2<5+1         True                  No

   (3,1)                  1>3         False             1<3+1         True                  No

   (4,2)                2>4         False            2<4+1         True                 No

Option 4: False

Ordered pair       y>x     Conclusion     y<x+1     Conclusion       Solution    

   (5,-2)              -2>5         False          -2<5+1         True                  No

   (-3,1)                1>-3         True            1<-3+1         False                 No

   (4,2)                2>4         False            2<4+1         True                 No

No any ordered pair for system for linear equality.

To check which ordered pair (point) is in the solution set of the system of given linear inequalities y>x, y<x+1; we just need to plug given points into both inequalities and check if that point satisfies both inequalities or not. If any point satisfies both inequalities then that point will be in solution.

I will show you calculation for (5,-2)

plug into y>x

-2>5

which is clearly false.

plug into y<x+1

-2<5+1

or -2<6

which is also false.

hence (5,-2) is not in the solution.

Same way if you test all the given points then you will find that none of the given points are satisfying both inequalities.

Hence answer will be "No Solution from given choices".

16 fluid ounces = 1 pint

so to find how many 1 pint containers you need to divide :

32 fluid ounces ÷ 16 fluid ounces = 2 pints

Question 1 of 10
Zanzabum

Answer:

A: 40 degrees

Step-by-step explanation:

Since every triangle is 180 degrees, you can start off by subtracting 50 from 180 since that side does not contain a y for you to solve.

Since the other two sides do have a y in them, you would set 130 degrees equal to y+10 and 2y:

130=y+10+2y

Then you would isolate the y's by subtracting 10, and you would add y and 2y together to get:

120=3y

Finally, you would divide 120 by 3 to get your answer, 40=y.

Hope this helps!
