She ran the last 100 meters in 2:15 -1:25 = 0:50, so her average speed was
... (100 m)/(50 s) = 2.0 m/s
Answer:
f(x) = -8(4)x
Step-by-step explanation:
The reflection of the point (x,y) across the x-axis is the point (x,-y).
Having said this, to reflect the function y=g(x) = 8(4x) over the x-axis, we just need to evaluate the equation in the point: (x,-y).
y = 8(4x) ⇒ -y = 8(4x) ⇒ y = -8(4x)
Then f(x) = -8(4x)
Attached you will find the graph of g(x) (blue) and f(x) (red),
9668
Explanation:
18 ones, 18x1=18
15 hundreds, 15x100 =1500
15 tens, 15x10=150
8 thousands,8x1000=8000
8x1000=800018+1500+150+8000=9668

Answer:
93 adult tickets
Step-by-step explanation:
Let 'a' represent the number of adult tickets sold. Then total revenue was ...
9.60a +5.80(167 -a) = 1322
3.80a = 353.40 . . . . . . . . . . subtract 968.60, collect terms
a = 93 . . . . . . . . . . divide by 3.8
93 adult tickets were sold that day.
__
