Answer:
Step-by-step explanation:
Applying logarithm rule
Log A - Log B= Log(A/B). Division rule
Now, Logx-log(x+13)=1
Log(x/(x+13))=1
Assume that the log is a natural log whose base is 10.
Then apply logarithm law
Log10 base 10=1
Comparing this to Log(x/(x+13))=1
This implies that
x/(x+13)=10
x=10(x+13)
x=10x+130
x-10x=130
-9x=130
x=130/-9
x=-14.444

please dont blame me if i get this wrong this is what i put.
Step-by-step explanation:
Using the following 3 equations, answer the questions:
11x + y =4, x+y = -2, x - 2y = 18
How can you determine which equations can be graphed more easily using x- and y-intercepts, rewriting in slope-intercept form, or using a table of values?
you can determin which is eiser to graph by wether or not they have numbers infront of the x and y intercepts. i find it mutch eiser if they allready have the numbers there. its also eiser to graph 11x + y =4 and x - 2y =18 on a slope intercept rather than table of values because you allready can find the points for those two eiser than the last one which would be used on the table of values. for the problem x+y=-2 you would use x and y intercepts. for 11x+y=4, rewriting in slope form is the corect method to use. and finaly use the table of values method for x-2y=18.
Which method works best for you personally? When does it not work as well?
the one that i find works best for me personally is probably gonna be the slope intercept method as apposed to many other methods. it doesnt work all the time because nothing can but normaly when i have a problem with this method i can just go to the table of values method and get the answer. (sorry if this is wrong this is what im putting for my answer. dont copy and paste this though if u do desiede to use it, read it and turn it into your own words so its not obvious you found the answer on the internet. and tbh i didnt read the lesson i just am ok at comming up with answers useing the question and getting away with it. )

Answer:
Hey! No need to fret ok so you are doing 7/6 the answer is 1.16 what do we know about this that is true.
Step-by-step explanation:
You are correct only the sum which is 1.16 is irrational because the product of the numbers is rational. Hope I help have a good day please put me for brainliest Thank You!
Answer:
14
Step-by-step explanation:
In point-slope form, the equation with slope -7 through point (3, 0) can be written ...
y = -7(x -3) +0
y = -7x +21 . . . . . eliminate parentheses
Here, we can see m=-7 and b=21, so ...
m+b = -7+21 = 14
The equation of the line is y = -7x + 21, and the value of m + b is 14.
The equation of a line can be written in the form y = mx + b. In this form, m represents the slope of the line and b represents the y-intercept. Since the slope of the line is given as -7, we can substitute -7 for m. The line also contains the point (3,0), which means that when x = 3, y = 0. Plugging these values into the equation, we can solve for b:
0 = -7(3) + b
0 = -21 + b
b = 21
Therefore, the value of m + b is -7 + 21 = 14.
