The midpoint of a line segment is the average of the endpoint's coordinates, mathematically:
mp=((x1+x2)/2, (y1+y2)/2)
In this case:
(-4,6)=((8+x)/2, (-2+y)/2)
(-8,12)=((8+x),(y-2))
(-16, 14)=(x,y)
Add all the numbers then divide them by the amount of numbers
509 divided by 10 = 50.9
If we assume that all students who were not sick came then
3/3-1/2=2/3 left
24 were at school
24=2/3 of all
times both sides by 3/2
72/2=all
36=all
there are 36 students
Answer:
Step-by-step explanation:
11. Write in point slope form first;
y+4 = (x+1)^2; Convert to standard form;
y=x^2+2x+1-4
y = x^2+2x-3; Final standard form
12. Convert the original point-slope form with the vertex given;
y-3 = a(x-4)^2; plug in the point (1,12) to solve for a;
12 -3 = a(1-4)^2
9 = 9a
a = 1
y-3 = (x-4)^2
y=(x-4)^2+3: Final vertex from
13. The vertex is at (-1,-4)
y +4= (x+1)^2; Factored form can mean many things;
this is the equation of the function; factor it how your teacher taught you.
