Read Solution (Total 1)

witches=4, ghosts=12,scarecrows=8

Let no of witches = x, ghost = y and scarecrows = z

x+y+z = 24 ---(1)
z = x+4 ---(2)
x = y-8 ---(3)

substitute (2) in (1)
2x+y = 20 --- (4)

substitute (3) in (4)

3x +8 = 20
x = 4
y=12
z=8

1. let f be a quadratic function with a minimum value of -22100, a line of symmetry of x = 140, and a y-intercept of (0,-2500).
2. the function g is the same as f but reflected about the x-axis and reduced by a factor of 200.
3. if x equals your grade
What is the value of g to one decimal place? Why is it true that a line perpendicular to y= 4x-3 would have the slope of -1/4??
