Step-by-step explanation:
A. 4(a + 1) = 2
= 4a + 4 = 2
= 4a = 2-4 = - 2
= a = - 2/ 4 = - 1/2
B. 3 - 9x = - 6-8x
3 + 6 = - 8x +9x
9 = x
C. 12x - 3 = 14x - 35
- 3 + 35 = 14x - 12x
32 = 2x
32 / 2 = x
16 = x
The pH of distilled water is usually LESS THAN 7, because when it contacts air CO2 gas begins dissolving into the water.
Step-by-step explanation:
-2x - 4 + 5y = 8
-2x + 5y = 8 + 4
-2x + 5y = 12

Answer:
( - x, - y )
Step-by-step explanation:
The starting is always Quadrant I.
270 degrees clockwise from Quadrant I is Quadrant III.
In Quadrant III, the points will be in the form ( - x, - y ).
