It's 
which gives 5.23 times increase in 10 years, so 523% of oryginal price
|–2x| = -6
=> 2x = 6
=> x = 3
and,
=> 2x = -6
=> x = -3.
Two points, one at negative 3 and one at 3.
Answer:
C
Step-by-step explanation:
In a parallelogram, consecutive angles are supplementary, sum to 180° , so
3y + 108 = 180 ( subtract 108 from both sides )
3y = 72 ( divide both sides by 3 )
y = 24 → C
Step-by-step explanation:
By Exterior Angle Theorem,
81° + b = 117°.
=> b = 117° - 81° = 36°.
