Answer:
4!
Step-by-step explanation:
using the slope formula and the points (-1, 0) and (-2, -4) on the line:
-4 - 0 / -2 - -1 = -4 - 0 / -2 + 1 = -4 / -1, and since both the top and bottom are negative, they make a positive, giving you a positive 4
the slope formula is rise/run, or y2 - y1 / x2 - x1!

Answer:
C) 7 ft 4 in
Step-by-step explanation:
Shadows are assumed to be proportional to the height of the object casting them. Hence the brother's shadow will satisfy ...
shadow/(6 ft) = (5.5 ft)/(4.5 ft) = 11/9 . . . . . reduce the fraction
shadow = (6 ft) · (11/9) . . . . . . . . . . . . . . . . . multiply by 6 ft
shadow = 7 1/3 ft = 7 ft 4 in
It is a function, that when set equal to 0 produces an equation that produces a parabola and that follows the format
Y = aX^2 + bX + c
