Sam is using the linear equation x-y= -5 to plot a graph. if the y coordinate is 7, what is the value of the x coordinate?
on 5th day and 13th day attendance was equal for both plays and it was
231 for each .
in order to find same attendance ,we need plug both equation equal
-x^2+26x+126 = 8x+191
-x^2+26x-8x+126-191 = 0
-x^2 +18x-65 =0
multiplying both sides by -1 ,we get
x^2 -18x+ 65 =0
(x-5) (x-13) =0
x =5 and x =13
on 5th day and 13th day attendance was same.
and attendance can be obtained by plugging x =5 in either of equation
y = 8(5)+191
= 40 +191
i think this question needs more information.
to figure out 110% of the students who walk, we need to know how many students walked to school.
step-by-step explanation: when you divide 3845 by 0.07 you get 553571.142857142857143. tto round to the nearest tenth means the first decimal point which woukd make the answer 55357.1
