A fish is swimming at a constant rate toward the ocean floor. The equation y = -7x - 3 can be used to represent this situation, where y is the depth of the fish in meters below sea level and x is the number of seconds the fish has been swimming.

Which statement best describes the depth of the fish, given this equation?

From a starting position of 7 meters below sea level, the fish is ascending 3 meters per second.

From a starting position of 3 meters below sea level, the fish is ascending 7 meters per second.

From a starting position of 3 meters below sea level, the fish is descending 7 meters per second.

Answers

Answer:

The answer is E.

Step-by-step explanation:

Plug all the values into the inequalities.

For these, we need only one equation to be true for the x's to work.

When those x-values are plugged in to the first equation, they are less than 18, so this equation doesn't work with our values.

The second equation does work, as all the values are less than or equal to -4. That means that anything in between those number would work as well, so E has to be the correct answer.

11) slope and y-intercept, if the answer ignore this if you do know the answer than plz answer

Answers

Answer:

Slope : -1

Y-intercept : (0,6)

Step-by-step explanation:

Answer:

Slope: -1

y-intercept: 6

Step-by-step explanation:

Lets figure out the slope with the formula, [tex]\frac{y2 - y1}{x2-x1}[/tex]. Take 2 coordinates and substitute them in. Lets take (-3,9) and (-1,7). Here are the steps:

[tex]\frac{7-9}{-1-(-3)}[/tex]

[tex]\frac{-2}{-1+3}[/tex]

[tex]\frac{-2}{2}[/tex]

[tex]-1[/tex]

Now we know that the slope is -1, so m = -1.

Lets figure out the y-intercept. We have to have an equation with the slope in it. Since we don't know the y-intercept yet, we will use the equation y = -x + b. Lets take the coordinate (5,1). Substitute the coordinates in. Here are the steps:

1 = -5 + b

b = 6

Now we know that the y-intercept is 6, so b = 6. I hope this helped!

The solution to the following equation is x=0
6x+7= 1/2x+7

True
or
False
(The 1/2 is a fraction)

Answers

Answer: True

Explanation:
If X=0 then that would make the problem 6(0)+7=1/2(0)+7. Anything multiplied by 0 is 0 so that would cancel the 6 and the 1/2. That means that you would be left with 7=7

Answer:

True

Step-by-step explanation:

To see if that is the solution, lets solve the equation.

6x + 7 = 1/2x + 7

Subtract 1/2x from each side to bring it to the right

6x - 1/2x + 7 = 7

Subtract 7 from each side to bring it to the left

6x - 1/2x = 7 - 7

Simplify it

5.5x = 0

Divide 5.5 from each side to leave x alone.

x = 0

The answer is true. I hope this helps!
