A researcher in a submarine begins at the surface of the ocean. The submarine descends 20.7 meters and then ascends 5.7. What is the depth of the submarine.

A. -26.3 meters
B. -14.9 meters
C. 14.9 meters
D. 26.3 meters

the formula of a slope:

we have the points (-2, 7) and (2, 3). substitute:

answer: c

(2, -4)

goes 7 to the

(9, 4)

easy

the solution is x=1

step-by-step explanation:

we are given our   equation as

let's assume

left side function is

right side function is

now, we can draw graph

and then we can get intersection point

the intersection point will be solution

so, the solution is

x=1
