Answer:
The answer is -2, -17
Step-by-step explanation:
You write a system of equations
![x_{1} +x_{2}=-19\\x_{1}-x_{2}=15](https://tex.z-dn.net/?f=x_%7B1%7D%20%2Bx_%7B2%7D%3D-19%5C%5Cx_%7B1%7D-x_%7B2%7D%3D15)
Then you solve:
-2, -17
I believe its 45 because a right angle equals 90 degrees and if you multiply 45 and 2, it'll give you a right angle(90 degrees)
Call the production cost 'C', the revenue 'R' and the number of CDs 'n':
C=2000+5n
R=10n
By definition Profit P = R-C, therefore P=10n-2000+5n = 5n-2000.
5/8=.625 and 7/15=.466 repeating so 5/8 is a bigger fraction
Slope intercept form is y=MX+b.
M is the slope, x is the x intercept, and b is the y intercept
the slope is
![\frac{ - 2}{1}](https://tex.z-dn.net/?f=%20%5Cfrac%7B%20-%202%7D%7B1%7D%20)
An intercept is where the formula crosses the axis. therefore, the x intercept is .5, and the y intercept is 1
so the point slope formula is
