Answer:
Step-by-step explanation:
The slope of line u is 9/2; the line perpendicular to that is the opposite reciprocal...opposite sign and the flip of the fraction. The perpendicular slope is -2/9
(3x-5)(3x-5)
Because it's (3x-5)²=9x²-30x+25
3x-6+4=-20
- add 6 to both sides
3x+4=-20 +6
3x+4=-14
- then subtract 4 from both sides
3x=-14 - 4
3x=-18
- then divide 3 from both sides
-18 divided by 3 = -6
x= -6
(2/5) / (9/1)
Flip second fraction and multiply instead of divide
(2/5) * (1/9)
= 2/45
