The answer is y = -13/7 + 3x/7
To find the tip of the bill. You will need to find how much of $86.40 is 20%. In this question, they're asking how much is the tip, not how much will the final price be.
When you multiply a percentage you move the decimal point 2 times to the left: 20. → .20
You would multiply $86.40 by .20
When you solve it 86.40 × .20 = 17.28
$17.28 is 20% of $86.40
$17.28 will be the amount he got for his tip.

Answer:
19 and 128
Step-by-step explanation:
19.3 is closer to 19 than 20 and 127.8 is closer to 128 than 127
Rcsc(theta) = 3
r/sin(theta) = 3
r =3sin(theta)
Now use the relation between polar coordinates and rectangular coordinates
x = rcos(theta)
y = r sin(theta)
=> x = [3sin(theta)]cos(theta)
x = 3 sin(theta)cos(theta)
and y = [3sin(theta)]sin(theta)
y = 3 [sin(theta)]^2
