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. ⠀ ⠀

Dan sold 40 concert tickets in 5 days.
olchik [2.2K]

Step-by-step explanation:

The number of tickets sold by Dan the first day is x.

Tickets sold on the 2nd day: x+3

on the 3rd day: x+6

on the 4th day: x+9

on the 5th: x+12

Since the total of tickets sold by Dan is 40:

x+(x+3)+(x+6)+(x+9)+(x+12)=40

5x+30=40

5x=10

x=2

number of tickets sold on the third day: 8
