Answer:

R1:   Given

R2:   Subtraction Property of Equality

R3:   Distribute Property

R4:   Addition Property of Equality

R5:   Division Property of Equality

Write a paragraph proof for the following conjecture: m∠1 + m∠2 = m∠4

Prove: m∠3 + m∠1 + m∠2 = 180°

Given: ∠1 + ∠2 = ∠ 4

∠4 + ∠3 must be 180° because they are supplementary

If ∠4 + ∠3 is 180, and ∠1 + ∠2 = ∠4, you can substitute ∠4 in the first equation for ∠1 + ∠2.

Hence, we arrive at the answer ∠1 + ∠2 + ∠3 = 180.

Write the perimeter of the triangle in<br> simplest form.
Genrish500 [490]

Answer:

6x +3

Step-by-step explanation:

Perimeter of a triangle is the sum of all the length of its sides. Since a triangle as 3 sides, add the 3 lengths together.

Perimeter of triangle= 2x -6 +x +8 +3x +1

<em>Bringing</em><em> </em><em>all</em><em> </em><em>the</em><em> </em><em>x</em><em> </em><em>terms</em><em> </em><em>together</em><em> </em><em>and</em><em> </em><em>constants</em><em> </em><em>together</em><em>:</em>

Perimeter of triangle= 2x +x +3x -6 +8 +1

<em>Simplify:</em>

Perimeter of triangle= 6x +3

Does this table show y as a function of x ? <br> : (-3,1) (0,-5) (4,7) (-3,0)
belka [17]

Answer:

No.

Step-by-step explanation:

The definition of a function is that every output (x) has only one input (y).

Here -3 gives two different outputs which contradicts the definition of a function.

What is the equation of the line, in general form, that passes through the point (1,1) and has a y-intercept of 2.
guajiro [1.7K]

Answer:

<h2>x + y - 2 = 0</h2>

Step-by-step explanation:

The slope-intercept form of an equation of a line:

y=mx+b

m - slope

b - y-intercept.

Put the given y-intercept b = 2 and the coordinates of the point (1, 1) to the equation:

1=1m+2            <em>subtract 2 from both sides</em>

-1=m\to m=-1

The equation of a line:

y=-1x+2\to y=-x+2

The general form of an equation of a line:

Ax+By+C=0

Convert:

y=-x+2          <em>add x to both sides</em>

x+y=2         <em>subtract 2 from both sides</em>

x+y-2=0
