Answer:
![\frac{1}{3}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B3%7D)
Step-by-step explanation:
The equation of the line is;
2(x - 3) - 6y = 10
Placing the line in slope intercept form we get;
6y = 2x - 6 - 10
6y = 2x - 16
Dividing throughout by 6 we get;
y =
x - ![\frac{16}{6}](https://tex.z-dn.net/?f=%5Cfrac%7B16%7D%7B6%7D)
Simplifying gives;
y = ![\frac{1}{3} x +2 \frac{2}{3}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B3%7D%20x%20%2B2%20%5Cfrac%7B2%7D%7B3%7D)
So the slope of this line = ![\frac{1}{3}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B3%7D)
Answer: uhh i cant really understand what your saying
Step-by-step explanation: :/
Answer:
11. C
Step-by-step explanation:
11.
y=1.75x+10
y=1.75(10.25)+10
So it's number C.
12.
y=1.75(10.25)+10
y=27.9375
He will collect $27.94
This is rounded.
Answer and explanation :
We have to prove
by using sum formula
We know that ![sin(A+B)=sinAcosB+cosAsinB](https://tex.z-dn.net/?f=sin%28A%2BB%29%3DsinAcosB%2BcosAsinB)
Now replace B = -B
So ![sin(A+(-B))=sinAcos(-B)+cosAsin(-B)](https://tex.z-dn.net/?f=sin%28A%2B%28-B%29%29%3DsinAcos%28-B%29%2BcosAsin%28-B%29)
We know that ![cos(-B)=cos(B)\ and \ and\ sin(-B)=-sinB](https://tex.z-dn.net/?f=cos%28-B%29%3Dcos%28B%29%5C%20and%20%5C%20and%5C%20%20sin%28-B%29%3D-sinB)
So
which we have to prove
