aleksley [76]

We will have the following:

Using exponential regression we will have that the line of best fit will be:

f\mleft(x\mright)=8585.658603*1.399211892^x

Now, we will have that:

\begin{gathered} 300000=8585.658603*1.399211892^x\Rightarrow34.94199034=1.399211892^x \\  \\ \Rightarrow x=\frac{ln(34.94199034)}{1.399211892}\Rightarrow x= \end{gathered}

So, the approximation using linear regression gives us as solution approximately 29.7 years; thus the closest one to match is then

-8 + 3h = 1 <br>i need help its a 2 step equation​
LekaFEV [45]

Answer:

h = 3

Step-by-step explanation:

-8 + 3h = 1

Add 8 to both sides.

3h = 1 + 8

Add 1 and 8 to get 9.

3h = 9

Divide both sides by 3.

h = \frac{9}{3}

Divide 9 by 3 to get 3.

h = 3
