Answer:
8x-6 brainliest please
Step-by-step explanation:
|7 - x| >= 1
When solving for x inside an absolute value, you can set up two equations. One for the positive and one for the negative(since we’re dealing with absolutes.
We end up with:
7 - x >= 1
7 - x <= -1 (inequalities’ signs flip when multiplying or dividing by a negative.)
7 - x >= 1
7 - 1 >= x
X <= 6
7 - x <= -1
7 + 1 <= x
X>= 8
X: (-infinity, 6]U[8, infinity)
Answer:
∠ ABC = 87°
Step-by-step explanation:
∠ ABD and ∠ DBE are adjacent angles and are supplementary, sum to 180° , so
2x - 17 + x + 32 = 180 , that is
3x + 15 = 180 ( subtract 15 from both sides )
3x = 165 ( divide both sides by 3 )
x = 55
Then
∠ DBE = x + 32 = 55 + 32 = 87° , thus
∠ ABC = ∠ DBE ( vertical angles )
∠ ABC = 87°
