Starts at 1,000feet
Each second is getting 20 feet closer to the surface since is ascending ( going higher)

1,000/20= 100/2=50 second it takes to reach the surface

Daniel had a 22-foot-long rope that he cut into eight equal pieces. Which equation can be used to determine the length, r, of ea
ivann1987 [24]

Answer:

Option C.

Step-by-step explanation:

Let

r-----> the length of each piece

we know that

To find the length of each piece, divide the total length of the rope (22 ft) by the number of pieces (8 pieces)

so

8r=22 -----> equation that represent the situation

r=\frac{22}{8}\ feet -----> the length of each piece

-2x - y = 1<br> -6x=3y+3
Natali5045456 [20]

Answer: All Real Number

Step-by-step explanation:

This is a system of equation, and generally, there are three ways to solve:

  • elimination
  • substitution
  • augmented matrix

Here, we are going to use elimination

------------------------------------------------------------------------------------

Given

-2x-y=1

-6x=3y+3

Put them in the same order

-2x-y=1

-6x-3y=3

Multiply 3 on both sides for the first equation

-6x-3y=3

-6x-3y=3

We subtract the first equation from the second equation

0=0

The answer will be All Real Numbers, which means any real number will fit this equation. In the graphing method, these two equations will overlap each other.

Hope this helps!! :)
