I have no clue actually this is weird
Step-by-step explanation:
yea the answer us 8dj but u jejrjfjfjdjdjjfjfjcj
|PR| = |PQ| + |QR|; |PQ| = |QR| conclusion |PR| = 2|PQ|
|PQ| = 3y; |PR| = 42; |QR|=?
subtitute
42 = 2(3y)
6y = 42 |divide both sides by 6
y = 7
|QR| = 3(7) = 21
Answer:
u = 7
Step-by-step explanation:
Using the slope intercept formula:

Substitute our values from the points and the known slope:

Now we multiply both sides by (8 - u) to isolate the x:
(8-u) x
= -7 (8 - u)
Next we add 56 to both sides:
-7 = -56 + 7u
Finish off by dividing both sides by 7:
7u = 49
u = 7
Answer:
1
Step-by-step explanation:
None of these numbers are alike terms so the only number left is 1.
