Answer:
y=2
Step-by-step explanation:
1/3 (y+7) = 3(y-1)
Multiply each side by 3 to get rid of the fraction
3*1/3 (y+7) = 3*3(y-1)
y+7 = 9(y-1)
Distribute
y+7 = 9y - 9
Subtract y from each side
y+7-y = 9y-y-9
7 = 8y -9
Add 9 to each side
7+9 = 8y-9+9
16 = 8y
Divide each side by8
16/8 = 8y/8
2 = y
Answer:
subtract 2a + 3b - 3b =5 - 3b
simply 2a = 5 -3b
divide both sides by 2 . 2a over 2 = 5 over 2 - 3b over 2
simply a= 5- 3b over 2

Answer:
(b = 5 StartRoot 3 EndRoot)
and
(b = Negative 5 StartRoot 3 EndRoot)
Step-by-step explanation:
we have
we know that
The roots of the quadratic function are the values of x when the value of the function is equal to zero
so
For f(b)=0
Solve for b
Adds 75 both sides
take square root both sides
Simplify
therefore
(b = 5 StartRoot 3 EndRoot)
and
(b = Negative 5 StartRoot 3 EndRoot)
