1) a= -1,  2) n=-2

3) x=4,   4) n=0

5) r=1,     6) r=2

7) No\,\,solution,     8) p=-12

9) m=2,    10) a=-3

11) x=4       12) n=-2

Step-by-step explanation:

We need to solve each equation.

1) 6a+5a = -11

Solving:

Adding like terms:

11a = -11

Divide both sides by 11

a= -1

2) -6n-2n=16

Solving:

Adding like terms:

-8n=16

Divide by -8

n=-2

3) 4x+6+3=17

Solving:

Adding like terms:

4x+9=17

Subtract 9 on both sides:

4x=17-9

4x=8

Divide both sides by 4

x=4

4) 0=-5n-2n

Solving:

0=-7n

Divide both side by -7

n=0

5) 6r-1+6r=11

Solving:

12r-1=11

Adding 1 on both sides

12r=12

Divide both sides by 12

r=1

6) r+11+8r=29

Solving:

9r+11=29\\9r=29-11\\9r=18\\r=2

7) -10=-14v+14v

Solving

-10=-14v+14v\\-10\neq 0\\No\,\,solution

8) -10p+9p=12

Solving:

-10p+9p=12\\-p=12\\p=-12

9) 42=8m+13m

Solving:

42=8m+13m\\42=21m\\m=42/21\\m=2

10) a-2+3=-2

Solving:

a-2+3=-2\\a+1=-2\\a=-2-1\\a=-3

11) 18=3(3x-6)

Solving:

18=3(3x-6)\\18=9x-18\\18+18=9x\\36=9x\\x=36/9\\x=4

12) 30=-5(6n+6)

Solving:

30=-5(6n+6)\\30=-30n-30\\30+30=-30n\\60=-30n\\n=60/-30\\n=-2

Find the equation of an exponential function in the form y = ab^x, given the points (0, 3) and (2, 108/25). Please simplify your
lilavasa [31]

We have the equation:

y=a\cdot b^x

We know two points and we will use them to calculate the parameters a and b.

The point (0,3) will let us know a, as b^0=1.

\begin{gathered} y=a\cdot b^x \\ 3=a\cdot b^0=a \\ a=3 \end{gathered}

Now, we use the point (2, 108/25) to calcualte b:

\begin{gathered} y=3\cdot b^x \\ \frac{108}{25}=3\cdot b^2 \\ 3\cdot b^2=\frac{108}{25} \\ b^2=\frac{108}{25\cdot3}=\frac{108}{3}\cdot\frac{1}{25}=\frac{36}{25} \\ b=\sqrt[]{\frac{36}{25}} \\ b=\frac{\sqrt[]{36}}{\sqrt[]{25}} \\ b=\frac{6}{5} \end{gathered}

Then, we can write the equation as:

y=3\cdot(\frac{6}{5})^x
