Mellisa is an expert scuba diver. she's down in the pacific ocean, looking for a rare type of sunfish. at one point, she is 29 meters below the surface of the water.
a. as she swims around for the fish, she swims for 12 mins and rises upward by 15 meters. what is her final depth at the end of the 12 minutes?
b. later in her dive, mellisa is at a depth of 40 meters. she decides to rise toward the surface very slowly. every minute, she rises 2 meters. if she does this for eight minutes, what is her depth?

A. 14 meters

B. 24 meters

Step-by-step explanation:

A. Mellisa starts at 29 meters deep, then rises 15 meters.  So her final depth is 29 − 15 = 14 meters.

B. Melissa starts at 40 meters deep, then rises 2 m/min for 8 minutes.  That means she rises a total distance of 2 × 8 = 16 meters.  So her final depth is 40 − 16 = 24 meters.

i think it is d. hope this

d: (13,-1)

step-by-step explanation:

we know the starting point is (1,5)

the ending point is (x,y)   (cristians house)

the total distance is 6 units (5: 1)  

the fast food restaurant is at (11,0) and is 5/6ths of the way from the starting point to the ending point

ending minus starting point * 5/6   is how far they went

(x-1) *5/6, (y-5) * 5/6

we then need to add the starting point to determine the location

5/6(x-1) + 1, (y-5) * 5/6 + 5

this equals the fast food location of 11,0

setting the x locations equal

5/6 (x-1) +1 =11

subtracting 1 from each side

5/6 (x-1) +1-1 =11-1

5/6(x-1) =10

multiplying by 6/5 on each side

6/5*5/6(x-1) = 10*6/5

x-1 =12

add 1 to each side

x-1+1 =12+1

x=13

do the same for the y coordinate

(y-5) * 5/6 + 5 =0

subtract 5 from each side

(y-5) * 5/6 + 5-5 =0-5

5/6 (y-5) = -5

multiplying by 6/5 on each side

6/5*5/6 (y-5) = -5 *6/5

y-5 = -6

add 5 to each side

y-5+5 = -6+5

y=-1

the ending point , or the coordinates of cristians house is

(13,-1)
