Answers:
The length of XY is 4
The length of ZW is 6
Because we don't get the same length (for XY and ZW), this means that the segments are not congruent.
-------------------------------------------------------------
To find the length of segment XY, you can count the number of spaces between -7 and -3 to get 4 units. Or you can subtract and use the absolute value notation to ensure the result is positive
|-7-(-3)| = |-7+3| = |-4| = 4
Do the same for segment ZW.
|2-8| = |-6| = 6
Answer:
57
Step-by-step explanation:
a) 8 -5v-3 = 5v-5
-5v+5 = 5v-5
identity
b) 3m-6 =4m+7
has 1 solution
c) 2w +4 = 5w -2w +4
2w+4 = 3w+4
w=0
one solution
d) 7y+9 = 7y-6
subtract 7y from each side
9=-6 impossible
no solution
Choice D
Answer:
b. The boundary line of y < 2x - 3 is not a solid line.
Step-by-step explanation:
It's a linear inequality thus its boundary line must be a solid line.
