Y=kx
12=15k
12/15=k
12/15=0.8
16=0.8x
16/0.8=x
16/0.8=20
to check 20*0.8=16
Answer:
The rate of change is $12/photo and the sitting charge would be 15.
y = 12x + 15
Step-by-step explanation:
Multiply 6 * 12 and subtract that from 87.
6 * 12 = 72
87 - 72 = 15
Answer:
(5*sqrt(2), 5pi/4)
Step-by-step explanation:
In Polar coordinates, tan(theta)=y/x and r=sqrt(x^2+y^2)
tan(theta)=-5/5=-1. Theta=5pi/4
r=sqrt(5^2+5^2)=5*sqrt(2)
Hence the Polar coordinate is (5*sqrt(2), 5pi/4)
