The slope of the given line is 1/3.

The perpendiculars all have the negative reciprocal slope, -3.

<span>A. y + 2 = -3(x-4)

Yes, slope -3.

B. y - 5 = 3(x+11)

No, slope 3.

C. y = -3x - 5/3

Yes, slope -3.

D. y = 1/3  x - 2

No, that's slope 1/3.

E. 3x + y = 7
</span>
That's

y = -3x + 7

Another slope -3, Yes.

Can someone please help super short
insens350 [35]

Answer:

542, 543, 544, 545.

Step-by-step explanation:

Divide 2174 by 4 = 543.5  

(because there are 4 integers) 543.5 is not an integer.

However, one of the four integers is 543.

Write down four consecutive numbers that include 543 and add them:  

like 541+542+543+544 =. if that is 2174, you have the answer, if it's too low, try moving up one number, like

542+543+544+545 = if it's still too low, move up one number again  

543+544+545+546=  

You only have to do that a max of 3 times to get the answer.

The four consecutive integers are  

542, 543, 544, 545.

<em>good luck, hope this helps :)</em>

What is the measure of ∠x?
Dima020 [189]
The angle is a complementary angle so both angles add up to 90 degrees

Therefore set your equation equal to 90 to find angle of x

53+x=90

Subtract 53 from both sides

X= 37 degrees

Exactly how many planes contain points J, K, and N? 0 1 2 3
Lapatulllka [165]
Answer: 1

A plane is uniquely defined by 3 distinct points. Think of a stool with 3 legs. Each part of the leg that makes contact with the ground allows the stool to stay stable. It turns out that that extra 4th leg may make the stool wobbly which is why 3 legs are preferred.
