Answer:
multiple choice is worth 2
short response is worth 4
Step-by-step explanation:
23x + 10y = 86
28x + 5y = 76
solve by elimination
multiply the top by -1 and the bottom by 2
-23x + -10y = -86
56x + 10y = 152
add them
33x = 66
x = 2
with x = 2 plug x into one of the equations
23x + 10y = 86
23(2) + 10y = 86
46 + 10y = 86
10y = 40
y = 4
x = 2 and y = 4 so
multiple choice is worth 2
short response is worth 4
Answer:
its the first one
Step-by-step explanation:
It's the first answer choice.
Steps:
-3x^2y^2x^4
(Apply the exponent rule)
x^4x^2 = x^2+4 = x^6
= -3x^6y^2
The correct choices based on the Segment Addition Postulate are <u>C. WX + XY + YZ = WZ</u> and <u>E. WY + YZ = WZ</u>.
<h3>What is a segment addition postulate?</h3>
A segment addition postulate is a part of a segment line that consists of two endpoints and all of the points between them.
For example, the segment addition postulate of line segment, AC will be defined as the sum of the lengths of the segments, AB and BC being equal to the total length AC.
<h3 />
The possible addition postulates that can be created from WZ are:
WZ = WX + XY + YZ
WZ = WY + YZ
WZ = WX + XZ
Thus, the correct choices of the segment addition postulate are <u>Options C and E</u>.
