find the difference. 14.3 - (-4.3)

Answers

The answer is 18.6. The double negative (minus a negative) equals a positive. So you add 14.3 + 4.3 = 18.6
14.3 - (-4.3). the negative will turn into a plus sign since a minus a negative will be positive. so, 14.3 + 4.3 = 18.6!

Answer:

The relationship is not a function

Step-by-step explanation:

Let angle 1, angle 2, and angle 3 have the following relationships.
Angle 1 and 2 are acute vertical angles
Angle 3 is an obtuse angle adjacent to both angle 1 and angle 2.
What is the sum of the measure of angle 1 and the measure of angle 3?

Answers

180 degrees

Vertical angles are opposite angles that share only a vertex. Since ∠3 is adjacent to both ∠1 and ∠2, this means that ∠3 shares a side and vertex with both of these angles.
This means that ∠3 and ∠1 form a straight line; this makes them a linear pair, which makes their sum 180°.

What is an Equation of a line?

The equation of a line is expressed as y = mx + b where m is the slope and b is the y-intercept

And y - y₁ = m ( x - x₁ )

y = y-coordinate of second point

y₁ = y-coordinate of point one

m = slope

x = x-coordinate of second point

x₁ = x-coordinate of point one

The slope m = ( y₂ - y₁ ) / ( x₂ - x₁ )

Given data ,

Let the equation of line be represented as A

Now , the value of A is

Let the first equation be P

2x - y = 8   be equation (1)

Let the second equation be Q

4x - 2y = 16  be equation (2)

Now , the slope of the line is m = ( y₂ - y₁ ) / ( x₂ - x₁ ) = 2

Substituting the values in the equation , we get

Divide equation (2) by 2 , we get

2x - y = 8   be equation (1)

Therefore , the value of equation (1) = equation (2)

Hence , there are infinite number of solutions to the equations
