Two vertical angles form a linear pair.
A. Always True
B. True in some cases
C. Always False
PLEASE ONLY ANSWER THIS QUESTION IF YOU 100% KNOW YOU HAVE THE ANSWER CORRECT!!!!

Answers

Answer: C) Always false

====================================================

Explanation:

A linear pair of angles satisfy these two requirements (both must be true)

The angles are adjacentThe angles are supplementary, ie they add to 180.

While it is possible for vertical angles to be supplementary (they both are 90), it is not possible for vertical angles to be adjacent. This is because vertical angles do not share a common side. Vertical angles are opposite one another, so they are as far from adjacent as possible, while still sharing a common vertex point however.

This means that vertical angles are never considered to be a linear pair. Put another way, you can ask yourself "can vertical angles form a straight line?". The answer is "they can never form a straight line". Again the fact they aren't adjacent is the reason why.

Find the constant of proportionality of the table and express it in an equation

Answers

Answer:

The constant of proportionality is 2.5. This can be expressed as (cups of sugar) * 2.5 = cups of flour

Step-by-step explanation:

The constant of proportionality is y/x. Since flour comes second, we'll plug flour in for y here.

5/2 = 2.5

15/6 = 2.5

20/8 = 2.5

The constant of proportionality is 2.5. This can be expressed as (cups of sugar) * 2.5 = cups of flour

It’s 2.5, lolookskkkdsk

I need to find the area, what is it?

Answers

Answer:

.75

Step-by-step explanation:

You have to do B * H / 2   which 1.5 x 1 = 1.5, and then 1.5/2 = .75

In order to find the area of a triangle, you must do 1/2 base x height.

So to plug in the numbers, you will have 1/2 x 1 x 1.5.

1/2 x 1 = 0.5 and 0.5 x 1.5 = 0.75

228

Step-by-step explanation:

First, let's find the area of A and C

5  ✕ 12 = 60

60 ✕ 2 = 120

Then B

8 ✕ 12 = 96

Then the triangles

3 ✕ 5 ÷ 2 = 12 / 2

But now think,because there are 2 triangles, so we have to times it by 2 later so we can just leave it like this.

120 + 96 + 12 = 228

help this is 7th grade mth

Answers

Answer:

y^8 goes to the last one

y^6 goes to the third one

y^5 goes to the second one

then the last one go to the first one

Answer:

(y)^-2 = 1/y^2, (y^3)^2 = y^6, y^8 -:- y^3 = y^5, and y^4 x y^4 = y^8

Step-by-step explanation:

When you divide y^8 -:- y^3, you subtract ^8-^3 = ^5, so its y^8 -:- y^3 = y^5

When you multiply y^4 x y^4, you add ^4 + ^4 = ^8, so it is y^4 x y^4 = y^8

When you multiply (y^3)^2, you multiply ^3 x ^2 = ^6, so its (y^3)^2 = y^6

And when you have a negative exponent,(^-2) you have to make it positive, so it would be y^-2 = 1/y^2

Determine whether the representation is proportional.y= -9x

Answers

Answer:

Yes it is

Step-by-step explanation:

y=-9x means that for every x value, the y value decreases by 9, so it is proportional because the value of y decreases the same amount each time. For example, if x=1, y=-9. If x=5, y=-45, and so on.

Yes it is proportional
