Y has a coefficient of 1 in the first equation, so it is easiest to use that one to write an expression for y.
... y = 20 - 2x . . . . . subtract 2x
Now, this expression can be substituted for y in the second equation.
Then, using the expression for y, we find its value
... y = 20 -2·7 = 6
The solution of the equations is (x, y) = (7, 6).
1.5 would be above 1, -4.5 would be below -2, 4 would obviously be above 1, 0.5 would be between -2 and above 1, and lastly -0.5 would be below -2. Hope this helped!
Answer:
25 miles
Step-by-step explanation:
In the year 2008 and 2009, the company had profit 2.5 thousand dollars and 1.75 thousand dollars consecutively
In the year 2010 and 2011, the company experienced a loss of 3.3 thousand dollars and 1.4 thousand dollars.
Total profit is 2.5 + 1.75 = 4.55 thousand dollars
Total loss = 3.3 + 1.4 = 4.7 thousand dollars
Total loss is bigger than the total profit so the company needs to make profit in 2012 to break even = 4.7 - 4.55 = 0.37 thousand dollars (this is the least profit the company needs to make)
A=bh => h=A/b
A=96 in^2
b=12 in
h=A/B=96 in^2/12 in = 96/12 in = 8 in.
Height = 8 inches
