There are currently 3 people signed up for the debate club. The school will not recognize the club officially until it has more
than 5 members. Which of the following graphs includes the possible values for the number of people who still need to sign up to make the club "official?" Number line with closed circle on 2 and shading to the left. Number line with closed circle on 2 and shading to the right. Number line with open circle on 2 and shading to the left. Number line with open circle on 2 and shading to the right.
y = mx + b slope(m) = 1.5 use either of ur points...(5,22.45)...x = 5 and y = 22.45 now sub and find b 22.45 = 1.5(5) + b 22.45 = 7.5 + b 22.45 - 7.5 = b 14.95 = b
so ur equation is : y = 1.5x + 14.95.......this means that each quart of oil costs $ 1.50 and the labor fee costs $ 14.95
Circumference is pi times diameter so that would equal 15 pi. The formula to find the area of a circle is A=pi * r^2 So you divide 15 by 2 to find the radius. r=7.5 Then you square it and multiply it by pi and get 56.25pi which is about equal to 176.715
