Step-by-step explanation:
2. 10x - 3 + 2x - 5 and 4(3x - 2)
10x - 3 + 2x - 5
Upon simplifying;
10x + 2x - 3 - 5
12x - 8
4(3x - 2)
Both expressions are equivalent - Yes!
3. 3y + 3 and 9(y + 1/3)
9(y + 1/3)
upon simplifying;
9y + 9 (1/3)
9y + 3
3y + 3
Both expressions are not equivalent - No!
4. 6(3x + 1) and 9x + 6 + 9x
6(3x + 1)
6(3x) + 6 (1)
18x + 6
9x + 6 + 9x
9x + 9x + 6

Answer:
145
In this geometry, the central angle (x°) and the external angle (35°) are supplementary.
x° = 180° -35°
x = 145
Answer: y=-1/4x+3
