Answer:

Step-by-step explanation:

First write the question as an equation

x+y = -5

2x+y = -2

From the given equations, we can create a third one.

x+y+2x+y = -7 or 3x+2y = -7

Use trial and error method for the possible values x and y

We know that at least one of these two have to be negative.

x can be 1, in which case y has to be 5.

Check this for

x+y ≠ -5

x can be -1

Try another one where x = -1 and y has to equal -2

Check this

X

x+y = -5

but,

2x+y ≠ -2

Another one,

Hi, can someone please help me? trying to graduate :(
ehidna [41]

Answer:

D

Step-by-step explanation:

the equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

here m = - 2 , then

y = - 2x + c ← is the partial equation

to find c substitute (3, - 2 ) into the partial equation

- 2 = - 6 + c ⇒ c = - 2 + 6 = 4

y = - 2x + 4 ← equation of line in slope- intercept form

Which of the following statements is false? -(-5) = 5 |-5| = -5 -|-5| = -5 -|5| = -5
TiliK225 [7]

Your question has been heard loud and clear.

Well -(-5)=5

5/-5/= -5

/-5/5= -5

So basically , the statement is false because   -5(-5) not equal to -5/-5/

Thank you

In how many different ways can the letters of the word 'CORPORATION' be arranged.
Komok [63]
Hey :)

The answer is 50400 ways

Because,
The word 'CORPORATION' has 11 letters.

It has the vowels 'O', 'O', 'A', 'I', 'O' in it and these 5 vowels should always come together.

These 5 vowels can be grouped and considered as a single letter. CRPRTN (OOAIO).

Hence we can assume total letters as 7. But in these 7 letters, 'R' occurs 2 times and rest of the letters are different.


Hope this helps!
