X - y = 1 x + y = - 9 a . (4, 5) b. (- 4, 5) c . (- 5, - 4) d . (- 4, - 5)

think the answer would beb

hey pal. the answer is b plz mark as brainliest

y - 25 = 2 ( x - 10 ) should be the answer

measurement of the swimming pool is given as = 7 yards 4.79 feet

first we will convert this to yards only.

1 foot = 0.33 yards

so, 4.79 feet = yards

so total yards are = yards

now we will convert this in meters.

1 yard = 0.914 meters

8.580 yards = meters

0.842 m = 0.842*100 = 84.2 cm

this becomes 7 meters and 84.2 cm

hence, the pool is 7 meters and 84.2 cm wide.
