Answer:
He has paid 5600 by the end of the year
your equation is: y=300x+2000
Step-by-step explanation:
x=12 because there is 12 months in a year
y=300(12)+2000
y=3600+2000
y=5600
The answer would be -36 because all i did is multiply -12 with 3 and you get -36.
hope this helped :)
Answer:
<h2> The third</h2>
Step-by-step explanation:
![(g\circ f)(x) = g\big(f(x)\big)](https://tex.z-dn.net/?f=%28g%5Ccirc%20f%29%28x%29%20%3D%20g%5Cbig%28f%28x%29%5Cbig%29)
so:
![I.\quad (g\circ f)(a)=\sqrt{f(a)}=\sqrt{a^2-4}=\sqrt{(a+2)(a-2)}\\\\II.\quad (g\circ f)(a)=2f(a)-2=2(\frac12a-1)-2=a-2-2=a-4\\\\ \bold{III.\quad (g\circ f)(a)=\sqrt{f(a)-5}-2=\sqrt{5+a^2-5}-2=\sqrt{a^2}-2=|a|-2}\\\\ IV.\quad (g\circ f)(a)=4f(a)-5=4(3-3a)-5 = 12-12a-5=-12a+7](https://tex.z-dn.net/?f=I.%5Cquad%20%28g%5Ccirc%20f%29%28a%29%3D%5Csqrt%7Bf%28a%29%7D%3D%5Csqrt%7Ba%5E2-4%7D%3D%5Csqrt%7B%28a%2B2%29%28a-2%29%7D%5C%5C%5C%5CII.%5Cquad%20%28g%5Ccirc%20f%29%28a%29%3D2f%28a%29-2%3D2%28%5Cfrac12a-1%29-2%3Da-2-2%3Da-4%5C%5C%5C%5C%20%5Cbold%7BIII.%5Cquad%20%28g%5Ccirc%20f%29%28a%29%3D%5Csqrt%7Bf%28a%29-5%7D-2%3D%5Csqrt%7B5%2Ba%5E2-5%7D-2%3D%5Csqrt%7Ba%5E2%7D-2%3D%7Ca%7C-2%7D%5C%5C%5C%5C%20IV.%5Cquad%20%28g%5Ccirc%20f%29%28a%29%3D4f%28a%29-5%3D4%283-3a%29-5%20%3D%2012-12a-5%3D-12a%2B7)
Yes it is
It means whatever the x value is the y value will equal 2.7 making it just a horizontal line
