(4,-1) turns into (1,4) because the equation for that is (x,y)->(y•-1,x)
The given equation, a = (2b + 10) / 6, solved for b is b = 3a - 5
<h3>Solving an equation for a variable</h3>
From the question, we are to solve the given equation for b.
From the given information,
The given question is
a = (2b + 10) / 6
Now, to solve the given equation for b, we will make b the subject of the relation.
Solving the equation for b
a = (2b + 10) / 6
Multiply both sides of the equation by 6
6 × a = 6 × (2b + 10) / 6
6a = 2b + 10
Subtract 10 from both sides of the equation
6a - 10 = 2b + 10 - 10
6a - 10 = 2b
Divide through by 2
6a/2 - 10/2 = 2b/2
3a - 5 = b
Therefore,
b = 3a - 5
Hence, the equation solved for b is b = 3a - 5

Answer:
Step-by-step explanation:
We first need to figure out what the equation is for this set of circumstances before we can answer any questions. We will use the equation
which is just another form of an exponential equation where
(1 + r) is the growth rate, P is the initial investment, and t is the time in years. We will fill in the values we know first to create the equation:
which simplifies to
Now we'll just sub in a 1 for t and solve, then a 2 for t and solve.
When t = 1:
A(t) = 4000(1.11) so
A(t) = 4440
When t = 2:
which simplifies to
A(t) = 4000(1.2321) so
A(t) = 4928.40
