The adult tickets cost $5 and the child tickets cost $2
Monday
5 x ($2) + 3 x ($5) = $25
Tuesday
4 x ($2) + 4 x ($5) = $28
8-3(2)
8-5
=3
the answer should be 3 after plugging in the variables.
Use completion of sq method
x^2+y^2+14x+10y-7=0
(x+7)^2+(y+5)^2=7+49+25
(x+7)^2+(y+5)^2=81
so centre is(-7,-5) radius is9
Given that the first time a census was taken in Esinville, the population was 12,621, then the <span>coordinates of the point that contains the y-intercept is (0, 12,621)
