Answer:
y=3×-11
Step-by-step explanation:
y=m+c
m=7-1÷6-4
m=6÷2
m=3
y=3+c
7=3(6)+c
7-18=c
-11=c
y=3×-11
Answer:
cos-1(-4/14)
Step-by-step explanation:
If
4.5=r
3.5=s
2=t
By law of cosines:
![r^{2}=s^{2}+t^{2} -2st cosR\\\\CosR= \frac{r^{2} -s^{2} -t^{2} }{-2st} \\\\R=cos^{-1} (\frac{(4.5)^{2}-3.5^{2} -2^{2} }{-2(3.5)(2)} )\\R= cos^{-1} (-\frac{4}{14} )](https://tex.z-dn.net/?f=r%5E%7B2%7D%3Ds%5E%7B2%7D%2Bt%5E%7B2%7D%20%20-2st%20cosR%5C%5C%5C%5CCosR%3D%20%5Cfrac%7Br%5E%7B2%7D%20-s%5E%7B2%7D%20-t%5E%7B2%7D%20%7D%7B-2st%7D%20%20%5C%5C%5C%5CR%3Dcos%5E%7B-1%7D%20%28%5Cfrac%7B%284.5%29%5E%7B2%7D-3.5%5E%7B2%7D%20-2%5E%7B2%7D%20%20%7D%7B-2%283.5%29%282%29%7D%20%29%5C%5CR%3D%20cos%5E%7B-1%7D%20%28-%5Cfrac%7B4%7D%7B14%7D%20%20%29)

Answer:
l = 0.13x+1025
Step-by-step explanation:
Let the monthly sales be x
Monthly income = $1025 + 13% of monthly sales
Monthly income = $1025 + 0.13x
Since l represent the monthly income
l = 1025+0.13x
Rearrange
l = 0.13x + 1025
Hence the linear equation representing the statement is l = 0.13x+1025
