A submarine at the surface dives 375 ft and then another 175 ft. express the final depth as an integer. a. –525 ft
b. –550 ft
c. 550 ft
d. 525 ft

Answers

Answer 1
Answer:

Answer: Hello mate!

If we consider y = 0ft in the surface (the initial position of the submarine)

When the submarine does the first dive, it descends 375ft

then the position is y = 0ft - 375ft = -375ft

where the position is negative because the submarine is descending.

Now, the submarine decends another 175ft, so the new position is:

y = -375ft - 175ft = -550ft

can you write an equation by setting an expression equal to itself. would an equation like this be true

Answers


Of course !  An expression is always equal to itself.

But if there's, say, an 'x' in the expression, then such an equation would be true
for x=every possible number.  You might say it has an infinite number of solutions ...
which certainly has to be true, because no matter what you do to an expression,
it's still always equal to itself !

 
yes it would be as long as it truly equals eachother

Which list of ordered pairs represents solutions to x + y = 2 ? (-4, 6), (0, 2), (4, 2) (-4, -6), (0, 2), (4, 2) (-4, 6), (0, 2), (4, -2)

Answers

The coordinates simply have to be plugged into the equation and determine whether the result is 2.
-4 + 6 =  2
0 + 2 = 2
4 + 2 =  6
-4 + -6 = -10 
0 + 2 =  2
4 + 2 = 6
-4 + 6 = 2
0 + 2 = 2
4 + -2 = 2

The solutions (without repeating pairs) are:
(-4, 6), (0, 2), (4, -2)

Answer:

C: (-4, 6), (0, 2), (4, -2)

Abcd is a rectangle. Find the length of each diagonal. .AC= 3y/5 BD=3y-4

Answers

Answer:

AC = BD = 1 unit

Step-by-step explanation:

 Given : length of diagonal of rectangle ABCD  AC=(3y)/(5) and BD=3y-4

We have to find the length of diagonal.

We know In rectangle diagonal are of equal lengths.

Therefore, for rectangle ABCD diagonals AC= BD

Substitute the values, we get,

(3y)/(5)=3y-4

Cross multiply , we get

3y=5(3y-4)

On simplyfy , we get

3y=15y-20

Solve for y , we get

15y-3y=20

12y=20

Divide both side by 12, we get,

y=(20)/(12)=(10)/(6)

Thus, put the values of y in AC and BD to find the length of diagonals , we get,

AC=(3y)/(5)=(3)/(5)*(10)/(6)=1

Similarly for BC, we get,

BD=3y-4=3((10)/(6))-4=5-4=1

Thus, AC = BD = 1 unit

I hope this helps you
