the points (3, 24) and (7, 56) represent points of a function where y, the number of photographs, varies directly with x, the number of pages in an album. which statement describes another point on the graph of this function? a 50-page photo album holds 400 photographs. an 80-page photo album holds 560 photographs. a 100-page photo album holds 8,000 photographs. a 900-page photo album holds 8,400 photographs.

Option A is correct. a 50-page photo album holds 400 photographs

The slope is used to determine the steepness of a line.

Give the coordinate points (3, 24) and (7, 56)

Since y varies directly with x, we need to get the slope to determine the correct

This shows that for every 8 number photographs, we can have 1 number of pages in an album.

1 page = 8 photographs

For 50 pages

50pages = x

1/50 = 8/x

x = 8×50

x = 400 photograpghs.

Hence we can conclude that a 50-page photo album holds 400 photographs

step-by-step explanation:

given perimeter: 28cm

length: 9cm

atp,

2(l+w)=p of the reactangle

2(9+x)=28

18+2x=28

2x=28-18

x=10/2

x=5

therefore width is 5 cm
