Answer: should be -1/ sqrt of 3. If it asks to rationalize it could be -sqrt of 3/3
Step-by-step explanation:
Answer :A)-2
Step-by-step explanation: If you multiply B; x + 9y =10 by -2 you will have -2 x+ -18y= -20. Then when you add B with a 2x + 8y = 5
-2x +-18y=-20
=0 +-10y=-15
Answer:
y ≈ 9.24
Step-by-step explanation:
Using the cosine ratio in the right triangle.
cos30° = 
= 
( multiply both sides by y )
y × cos30° = 8 ( divide both sides by cos30° )
y = 
≈ 9.24 ( to the nearest hundredth )
