Answer:
y = (-8)/9
Step-by-step explanation:
Solve for y:
14 - 9 y = 22
Subtract 14 from both sides:
(14 - 14) - 9 y = 22 - 14
14 - 14 = 0:
-9 y = 22 - 14
22 - 14 = 8:
-9 y = 8
Divide both sides of -9 y = 8 by -9:
(-9 y)/(-9) = 8/(-9)
(-9)/(-9) = 1:
y = 8/(-9)
Multiply numerator and denominator of 8/(-9) by -1:
Answer: y = (-8)/9
Answer:
-8/9
Step-by-step explanation:
2 x − 9 y = 22
x=7
- 2*7-9y=22
- 14-9y=22
- 9y=14-22
- 9y=-8
- y= -8/9

I'm pretty sure that's the correct answer..
is comounded yearly formula
rat ie 4.5%
P=47000
solve for when A=63000
divide both sides by 47000
take the ln of both sides
divide both sides by ln(1.045)
