Answer:
A linear formula for S as a function of D is S=17D+1534
Step-by-step explanation:
We are supposed to find a linear formula for S as a function of D.
Equation of line : y = mx+c
We are given that At the surface, the speed of sound is 1534 meters per second.
c = 1534
We are given that for each increase in depth by 1 km, the speed increases by 17 m/s
So, Slope = m = 17
Substitute the values in equation
y=17x+1534
x denotes depth
y denotes speed
We are given that Use D for depth and S for the speed of sound
So, S=17D+1534
Hence a linear formula for S as a function of D is S=17D+1534

Answerc:
Step-by-step explanation:
Answer:
x = 0
Step-by-step explanation:
-x/3 + 7 = -2x + 7
Subtract 7 from both sides.
-x/3 = -2x
Add 2x to both sides.
5/3x = 0
x = 0
