SELECT ALL The Points that are on the Graph of the line 3x + 2y = 28 (:
Oksana_A [137]
<h2>Answer:</h2>

<h3>(0,14) and (2,11)</h3>

<h2>Step-by-step explanation:</h2>

points are on the graph of the line:-

\tt{3x+2y=28  } ⠀

we get,

\rightsquigarrow \tt{ 2y=28-3x } ⠀

\rightsquigarrow \tt{y=\dfrac{28-3x}{2}  } ⠀

In,(0,14)

If we put the value ,x=0

y=\tt{\dfrac{ 28-3×0}{2}=\dfrac{28}{2}=14 }

So,we get one point,(0,14)✔

In,(2,11)

If we put ,x=2

y=\tt{\dfrac{28-3×2}{2}=\dfrac{28-6}{2}=\dfrac{22}{2}=11  }

so,we get another point (2,11)✔

in other given ponts{(1,12),(4,9),(8,4)},It is impossible. ⠀ ⠀

The difference between the set of non-negative real numbers and the set of positive real numbers is:
Inessa05 [86]

Answer:

C; A singleton set

Step-by-step explanation:

Mathematically, when a number is non-negative; it is either positive or zero

Now, this is because 0 identifies as neither a positive or a negative number

hence, when we find the difference between the two sets, the only number that stands out unmatched is the value 0

What this mean is that we are having a set with a single number result

So we have our answer as {0}

Which is a singleton set
