Answer:
The answer is 42 ansd to find the answer plug in -8 for x.
Step-by-step explanation:
f(-8) =3(6-(-8))
f(-8)=3(6+8)
f(-8)=3(14)
f(-8)=42

Answer:
The circle is centered at (5, −7) and has a radius of 7.
Step-by-step explanation:
The standard form of the equation of a circle with center (a,b) and radius r is given as:
![( {x - a)}^{2} + {(y - b)}^{2} = {r}^{2}](https://tex.z-dn.net/?f=%28%20%7Bx%20-%20a%29%7D%5E%7B2%7D%20%20%2B%20%20%7B%28y%20-%20b%29%7D%5E%7B2%7D%20%20%3D%20%20%7Br%7D%5E%7B2%7D%20)
The given equation is
![( {x - 5)}^{2} + {(y + 7)}^{2} = 49](https://tex.z-dn.net/?f=%28%20%7Bx%20-%205%29%7D%5E%7B2%7D%20%20%2B%20%20%7B%28y%20%20%2B%207%29%7D%5E%7B2%7D%20%20%3D%20%2049)
We rewrite to look like the stay form:
![( {x - 5)}^{2} + {(y - - 7)}^{2} = {7}^{2}](https://tex.z-dn.net/?f=%28%20%7Bx%20-%205%29%7D%5E%7B2%7D%20%20%2B%20%20%7B%28y%20%20%20-%20%20-%20%207%29%7D%5E%7B2%7D%20%20%3D%20%20%20%7B7%7D%5E%7B2%7D%20)
We now compare the two equations to get:
a=5, b=-7 and r=7.
Therefore the circle is centered at (5,-7) and has a radius of 7
Answer:
-8
Step-by-step explanation:
Area = 1/2 x B x H
1/2 x 28.3 x 12.8 = 181.12
