After visiting the Titanic, Captain Brain and Mr. Pinky are taking the Alvin submarine back to the surface of the water. They start 1700 feet under water. After ascending for 6 hours, they are 1580 feet below the surface of the water. (Note: under the water is negative) Write an equation to model this situation (use d for depth in meters and x for hours).

d = -20x + 1700

Step-by-step explanation:

First, you need to identify how many meters the submarine travels in an hour. In order to figure this out, you need to know how far they traveled in 6 hours.

In 6 hours, they traveled 1700-1580 meters or 120 meters.

If you divide both values by 6, you'll get that they traveled 20 meters every hour. Now you can write the equation:

depth = 1700 meters - 20 meters (# of hours)

d = 1700 - 20x

positive

step-by-step explanation:

the quadrant is facing upwards

answer:

it is general formula that is used to write value to its excet position

a11 a12 a13

a21 a22 a23

it is the example of order 2 by 3 matrix in this

a11 means value occur in 1 st row 1st column

a12 means value occurs in 1st row 2nd column

a13 means value occur in 1st row and 3rd column

a21 means value occurs in 2nd row and 1st column

a22 means value occurs in 2nd row and in 2nd column

a23 means value occurs in 2nd row and in 3rd column
