Answer:
x = 1.6 , y = 13.8
Step-by-step explanation:
y - 3x = 9 ( add 3x to both sides )
y = 9 + 3x → (1)
7x + y = 25 → (2)
Substitute y = 9 + 3x into (2)
7x + 9 + 3x = 25
10x + 9 = 25 ( subtract 9 from both sides )
10x = 16 ( divide both sides by 10 )
x = 1.6
Substitute x = 1.6 into (1)
y = 9 + 3(1.6) = 9 + 4.8 = 13.8

For each 16 unit increase in x, you get a 6 unit increase in y.
So, you can approach this with the idea of slope (change in y over change in x) to have a slope of 6/16 or 3/8.
y = 3/8 x
This checks out with all of those values.
Austin earns $9.75 an hour at a part-time job, and earns $12 each time mowing lawns in the neighborhood. They graph the amount of hours worked at the part-time job (X) and the number of lawns mowed (Y) to determine how to earn more than $300. Which type of boundary line should be used in the graph?HELP!
Answer:
$7.25 at part-time job
$9.00 every time lawn mowed
so he would get 33.33 day so we will just say 33 times to get 300 dollars if he gets $9 for mowing. And 41.37 hours to get $300 and he would have to use x and y graph to find the boundary line.
Step-by-step explanation:
Linear programming is a mathematical method that is used to determine the best possible outcome or solution from a given set of parameters or list of requirements,
Here, graph is attached in which boundary line is shown to earn more than $300 .
Let us consider that, Austin spend x hours in part time job and y times in mowing lawns.
Since, Austin earns $9.75 an hour at a part-time job,
In x hours, Austin earns = 9.75 x
Since, Austin also earns $12 each time mowing lawns
So, if he mowing lawns y times. he earns = 12y
Total earning = 9.75x + 12y
Since, Austin Austin wants to earn more than $300
Therefore, 9.75x + 12y > 300
Thus, boundary line for above equation shown in attached graph.

expand and simplify 3(f+3) + 2 (f+6)
Answer:
Step-by-step explanation:
3(f + 3 ) + 2(f +6) = 3*f + 3*3 + 2*f + 2*6
= 3f + 9 + 2f + 12
= 3f + 2f + 9 + 12 {Combine like terms}

The system is inconsistent because the slopes are the same and the lines are different.
A linear equation is of the form:
y = mx + b
where y, x are variables, m is the slope of the line and b is the y intercept.
Given the following system of equations:
y = 6x + 2 (1)
y = 6x + 1 (2)
We can see that both equations have the same slope of 6 but have different y intercepts.
Hence the system is inconsistent because the slopes are the same and the lines are different.
