Answer: The first one is not a function the second is a function the third one is not one and the fourth one is
Step-by-step explanation:
From the given points that are (3,1),(9,3),(27,9), we can say that x is three times of y. That is
x= 3y
And we need to solve for y. For that, we need to get rid of 3 from the right side by dividing both sides by 3 . And on doing so , we will get


or

Answer:
x = 6
Step-by-step explanation:
Assuming the equation is
-
= - 4
Multiply through by 6 ( the LCM of 3 and 2 ) to clear the fractions
2(2x + 3) - 9x = - 24
4x + 6 - 9x = - 24
- 5x + 6 = - 24 ( subtract 6 from both sides )
- 5x = - 30 ( divide both sides by - 5 )
x = 6
Answer:
It is US $44.00 Equivalent
Step-by-step explanation:
Using ratios (essentially fractions):
1 US : 75 JA
OR
1 US = 75 JA
Dividing both sides by 75 gives us:
US = 1 JA
So if we have 3300 JA we can multiply both sides to get:
44 US = 3300 JA
