Answer:

none of them

Step-by-step explanation:

The given line is, written in a more convenient way:

y = x + 3

I moved the (-1) to the right hand side, it became (+1) and summed with (+2) gave the (+3).

As you can see, the slope of your line is +1.

Now what do we know from the theory? We know that two lines are perpendicular if one's slope is the negative periodical of the other's.

In your case this is very easy to calculate. The negative reciprocal of +1 is -1.

The slopes of the five cases given as options are as follows:

1) -3

2) +3

3) -3

4) +1

5) -3

None of those lines is perpendicular to the original given line.

Answer:

none of them

Step-by-step explanation:

Two lines are perpendicular when satisfy the next equation: m1*m2 = -1, where m1 and m2 are the slopes o the lines.

line 1:  

y – 1 = (x+2)

y = x + 3

slope of line 1 = 1

line 2:  

y + 2 = –3(x – 4)

y + 2 = -3*x + 12

y =  -3*x + 10

slope of line 2 = -3

m1*m2 = 1*(-3 ) = -3

They are not perpendicular

line 3:  

y − 5 = 3(x + 11)

y − 5 = 3*x + 33

y = 3*x + 38

slope of line 3 = 3

m1*m3 = 1*3 = 3

They are not perpendicular

line 4:  

y = -3x –  

slope of line 4 = -3

m1*m4 = 1*(-3 ) = -3

They are not perpendicular

line 5:  

y = x – 2

slope of line 5 = 1

m1*m5 = 1*1 = 1

They are not perpendicular

line 6:  

3x + y = 7

y = -3x + 7

slope of line 6 = -3

m1*m6 = 1*(-3 ) = -3

They are not perpendicular

Why equals 3/4 X -12 and why equals negative 4X - 31
Helga [31]

Answer:

  (x, y) = (-4, -15)

Step-by-step explanation:

Perhaps you want the solution to ...

  y = 3/4x -12

  y = -4x -31

Equating the two expressions for y gives ...

  3/4x -12 = -4x -31

  3/4x = -4x -19 . . . . . add 12

  3x = -16x -76 . . . . . multiply by 4

  19x = -76 . . . . . . . . . add 16x

  x = -76/19 = -4 . . . . divide by 19

  y = (3/4)(-4) -12 = -15 . . . . use the first equation to find y

The solution to this system of equations is ...

  (x, y) = (-4, -15)

Which would the phrase "two times the quotient of a number and 3" look like as a variable expression?
Naya [18.7K]
2 n/3 would be the closest answer although it looks as if the 2 is supposed to be multiplied by n/3 which would lead me to write it as 2(n/3)

Pip was thinking of a number. Pip halves the number and gets an answer of 87.2. Form an
jeyben [28]

Answer:

x/2=87.2

Step-by-step explanation:

Pip was thinking of a number - Let's call this number x

Pip halve the number - So half of x = x/2  (or 1/2 x)

And gets an answer of 87.2  - x/2=87.2

So your equation would be x/2=87.2

I hope this helps :)
