Answer:
k=5
Step-by-step explanation:
remove parenthese, combine like terms, move terms, combine like terms, divide both sides
Answer:
x = 5
Step-by-step explanation:
(10/3)/5 = (x+1)/9
(10/3)9 = 5(x+1)
90/3 = 5x + 5
30 = 5x + 5
25 = 5x
x = 5
Answer:
See the graph and explanation below.
Step-by-step explanation:
For this case we have the following function:

The domain for this function is given by:
since the natural log is not defined for negative numbers
, 
We can calculate some points in order to see the tendency of the graph, we can select a set of points for example
and we can calculate the values for f(x) like this
x=5.5

x=6

That represent the x intercept
x=7

x=8

x=9

x=10

And that represent the x intercept
And then we can see the plot on the figure attached.
Step-by-step explanation:
7 + x/3 =2x - 5
7 + 5=2x - x/3
12 = 5x/3
cross multiply
36=5x
x=36/5
x=7.2
