What is7,498 rounded to the greatest place value????

Irina18 [472]

Answer:

7,000

Step-by-step explanation:

The answer is 7,000 because when rounding to the greatest value you basically keep on number and round the others since the 498 is lower than 500 you would keep the 7 and turn the other's into 0's hence 7,000.

SELECT ALL The Points that are on the Graph of the line 3x + 2y = 28 (:

Oksana_A [137]

<h2>Answer:</h2>

<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. ⠀ ⠀
