#2) A lifeguard is swimming to a drowning swimmer. The lifeguard's location is at (0,0) and the swimmer is at (8,5). How far (distance) is the lifeguard from the
swimmer?
9.43
89
6.24
3.61

Step-by-step explanation:

The formula for calculating the distance between two points is expressed as

D =√(x2-x1)²+(y2-y1)²

Given the coordinates (0,0) and (8,5)

D = √(5-0)²+(8-0)²

D = √5²+8²

D = √25 + 64

D = √89

D = 9.43

Hence the distance between the life guard and the swimmer is 9.43

step-by-step explanation:

the answer is y < -3 or   y > 3

-3y > 7 + 2

-3 y > 9

y < -3
