<u>Given </u><u>:</u><u>-</u>
- y = 2/3x + 4 .
<u>To </u><u> </u><u>Find</u><u> </u><u>:</u><u>-</u>
- The value of y when x = 0 .
<u>Solution</u><u> </u><u>:</u><u>-</u>
The given equation to us is ,
y = -2/3x + 4
So when we substitute x = 0 , we have ,
y = -2/3 *0 +4
y = 0 + 4
y = 4

Answer with Step-by-step explanation:
A 3 foot wide brick sidewalk is laid around a rectangular swimming pool.
The outside edge of the sidewalk measures 30 feet by 40 feet.
Length of swimming pool=(30-3-3) feet
=24 feet
Breath of swimming pool=(40-3-3) feet
= 34 feet
Perimeter of swimming pool=2(24+34) feet
(since perimeter of rectangle=2(l+b) where l is the length and b is the breath of the rectangle)
Perimeter of swimming pool=116 feet
Hence, Perimeter of swimming pool is:
116 feet
