13. 2/5 of the students like pizza. 30% of the students who like pizza also like barbeque ribs. There were 540 students
who took the survey. How many like pizza and barbeque ribs?

step-by-step explanation:

x^2 -12x + 36 + y^2 = 36

x^2 + y^2 = 12x

r^2 = 12rcos(theta)

r = 12 cos(theta)

6x = 48

i hope this . 6 cards each and a total of $48. dvide each side by 6 and you will have your answer.

y=3x+4

step-by-step explanation:

given the points a(0,4) and b(-4, -8)

eqn of line ab: (y-4)/(x-0)=(-8-4)/(-4-0)

(y-4)/x=-12/-4=3

y=3x+4
