Which ordered pair would form a proportional retationship with the points in the graph?
shtirl [24]

Answer:

(9, 6)

Step-by-step explanation:

the given points are

(3, 2)

(6, 4)

so, can you see, how the sequence continues ?

I see immediately that for every 3 additional units of x we add 2 units of y.

so, yes, the next point in the sequence is

(6 + 3, 4 + 2) = (9, 6).

so, this point (or ordered pair) follows the same ratio or proportional relationship between x and y as the points already in the graph.

in other words, they are on the same line following the same slope ("y coordinate change / x coordinate change" when going from one point on the line to another).

Danica has laid so they form a rectangle with a perimeter of 18 inches.What is the difference between the greatest and least pos
stealth61 [152]
Elemantary school so
area=legnth times width
to get greatest area, make legnth as close to width as possible in measure

to get least area, make legnth as far away from width as possible in measure
perimiter=2 times legnth+2 times width=2 times (legnth+width)
18=2 times (legnth+width)
divide 2
9=legnth+width
find closest and farthest
1+9 is farthest
4+5 is closest

areas=legnth times with
1 times 9=9
4 times 5=20
differnce is subtract
20-9=11

answe is 11
(note I didn't use decimals since the user is supposedly in elemenatry school)

umka2103 [35]
Both the original and the inverse are functions because for each value of C there is a unique value of F and vice-versa.
