Answer:

1. 3.333333333333...

2. 1

3. -5

1. -8 + 2( -3x + 9) = -10

-6x + 10 = -10

-6x = -20

x = 3.33333333...

2. 8x + 5(6x - 8) = -2

38x - 40 = -2

38x = 38

x = 1

3. -x + 3(4x +26) = 23

11x + 78 = 23

11x = -55

x = -5

Is the relationship shown by the data linear? x -9, -5, -1, 3 y -2,-7,-12, -17

Temka [501]

x y
------ -----
-9 -2
-5 -7
-1 -12
3 -17

ur x's all have a difference of 4, and ur y's all have a difference of -5...so yes, this is linear with a slope of (-7+2) / (-5 + 9) = -5/4

Define bisect and midpoint. Using constructions, draw and label an angle bisector and a perpendicular bisector. Show segment add

larisa [96]

Bisect is a word that means to divide a thing, line or a circle into two parts. While midpoint is known as the middle point that exist in a line segment.

<h3>What is Angle addition postulate?</h3>

This theory states that if two angles are said to be put beside each other, the resulting angle is said to be equal in terms of the sum of the two real angle measures.

Note therefore, that that Bisect is a word that means to divide a thing, line or a circle into two parts. While midpoint is known as the middle point that exist in a line segment.
