Answer:

(10,4,-3)

Step-by-step explanation:

(x,y,z)

z= -3 given

y+z = 1 (equation 2)

y-3 =1

y=4 (solve 2 after substation)

eq #1 : x + 4 - (-3) = 17

x+4+ 3 = 17

x+ 7 = 17

x=10

Answer:

(10, 4, -3)

Step-by-step explanation:

z = -3

y + z = 1

y - 3 = 1

y = 4

x + y - z = 17

x + 4 - -3 = 17

x + 4 + 3 = 17

x + 7 = 17

x = 10

(10, 4, -3)

A shark is at -80 feet. It swims up and jumps out of the water to a height of 15 feet. Write a subtraction expression for the ve

lilavasa [31]

Since the shark is in a deep water level of specifically 80 feet it is then represented by a negative coefficient. This is due to the vector quantity the measure represents as decelerating or sinking or downward in direction. As oppose the shark moves upward with a height of 15ft.
Thus the expression will be -80ft + 15 ft = -65ft is the displacement.
15ft is positive since the movement is upward and the displacement then from the origin to the point of last position is 65ft, negative.
