Answer:
The mean is 20
Step-by-step explanation:
17+19+21+23=80
80 div 4 = 20
38,000 - 18,000 = 20,000 ft
20,0000 ÷ 600
=33.3
= 33 minutes 20 seconds

Answer:
Hi, I think it's DEGF
Step-by-step explanation:
for y=x－2,
just move y=x down 2 units.
for x=－2,
it's the easiest one, just see if there is a vertical crossing －2 on the x-axis.
for－2x+4,
you can see it as move y=－2x up 4 units, and for y=－2x, you can find it out by sub (1,-2) and (0,0) onto the graph.
for x²-4,
see it as y=x² moved down 4 units. for y=x², it's simply a parabola which is symmetrical along y-axis and crossing (0,0). And remember that since the coefficient of x² is positive, the graph is open upward.
Hope this will help u!!
