Answer:
f(x) is reflected over the x-axis and vertically scaled by a factor of 3
Step-by-step explanation:
If you compare the two functions, you see that ...
g(x) = -3f(x)
Multiplication by -1 effects a reflection over the x-axis. (All y-values are transformed to their opposite.)
Multiplication by 3 is a vertical scaling by a factor of 3.
Taken together, f(x) is reflected over the x-axis and vertically scaled by a factor of 3.
Answer:
n how many ways can a president, vice president, and a secretary be chosen? It is 12X11X10. Permutation of n things taken r at a time: nPr=n!/(n-r)! 12P3=12*11*10*9!/9!= 12*11*10=1320 ways.

Answer:
It is not
Step-by-step explanation:
If you pythagores- a^2+b^2=c^2
You will get 4^2+6^2=8^2
16+36=64
52=64
This is not true
Answer:
the pattern step number of second step is added to number of balls used of first step to get number of balls used of second step
that is
1 + 2 ( number of balls added to pattern step number) = 3 (number of balls used)
in the same way
6 + 4 = 10 ( first blank )
5 + 10= 15 ( second blank)
15 + 7 = 22 ( third blank )
22 + 8 = 30 ( fourth blank)
Answer: D. 50
Step-by-step explanation:
the sum of opposite angles of a cyclic quadrilateral are always 180 degrees
80 +2x= 180
2x= 180 - 80
x= 100/2
x= 50
