Select allthe situations that can be modeled by the expression -80 ÷ 4.(multiple answers may be selected) A. Brady owed his mother $80. He repaid her $4. How much does her still owe?

B. The football team lost 80 yards in four plays. How many yards did they lose per play?

C. Sam owed $80 to four friends. If he owes the same amount to each friend, how much does he owe each friend?

D. Taya received $80 for her birthday. She spent the same amount at four different places. How much did she spend each time?

E. Amanda withdrew $80 from her account each day for 4 days. How much money did she withdraw in all?

if the eqn of the parabola is f(x) = (x-4)(x+2), we need to mult. this out to find the coordinates of the vertex.

then f(x) = x^2 + 2x - 4x - 8, and f(x) = x^2 - 2x - 8.

one way in which you can find the vertex is to calculate x = -b / (2a).   here, that comes to

        )

x = = 1.   f(1) = 1^2 - 2(1) - 8 = - 9.   vertex is at (1, -9).

        2(1) 

find another point on the curve:   let x=0, for which y=-8.   then (0, -8) is on the curve.   plot the vertex and this point and draw a smooth parabola thru both.

circle area = pi * radius^2

if diameter = 10 then radius = 5

circle area = pi * 5^2

circle area = pi * 25

circle area = 78.5398163397 square units

step-by-step explanation:

answer: the distance

step-by-step explanation:

to calculate the distance d of a line segment with endpoints (x1, y1) and (x2, y2) use the formula d (x2 x1)2 (y2 y1)2. to calculate the midpoint of a line segment with endpoints (x1, y1) and (x2, y2) use the formula

the answer is c. ⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀
