Answer:
Step-by-step explanation:
It can be solved analytically or graphically. Graphically is the fastest way if you know how to handle the two lines. Let's rearrange terms in either case:
<u>Graphic:</u> Red line is 
, solid blue line is 
, the thin extension is the parent line without the absolute value.
Solving the equation is equivalent to answer "when is the blue line higher than the red one?" Which obviously happens outside the two intercept points. Let's find the first coordinate of both - we don't really care what's the y coordinate of either point.
For the left point, the x coordinate is given by 
For the right point, we have
<u>Analytical:</u>
We split the problem in two parts: while the content absolute value is non negative, we have
Which admits as solutions all valeus of x greater than 1 (since both have to be satisfied at once, and values between 1/2 and 1 will not work for the second.
OR, with a negative quantity inside the absolute value, we get
which again is satisfied by all values of x less than -1.
Thus the solution is given by
Hey there!
For Part A, because the amount earned on Sunday isn't specified, we can call this additional income x. Because we're writing an expression, we don't need an equal sign. The expression will be (x + 14).
For Part B, "2 less than" will mean "– 2" and "twice than" will mean the amount of dogs that Alicia walked times 2. We can call the amount that Alicia walked y to avoid confusion with the last expression (though you could use whatever variable here) and your expression will be (2y – 2).
Hope this helped you out! :-)
Answer:
75+(-50)=75-50
Step-by-step explanation:
-let x be the profit made last week and y be the profit made this week.
-The two week profit/ loss is given as:
#We substitute actual values to calculate the profit/loss made:
Hence, the two-week combined profit is $25.00
