-2f(x) means it is reflected and has a negative slope.
and for the 2 it means that the graph is compressed horizontally by factors of units
if it's less than 2 it would have been stretched, but since it's greater than 1 it is compressed.
9.1 is probalby the number you are looking for
156-90
Bilal bought 156 candy boxes and gifted 90 of them to one of his friends birthday .So calculate how many candy boxes he is left with .
Answer:
B.
Step-by-step explanation:
B.
- 9 ≤ - 3x - 6 ≤ 6
1 part.
- 9 +6 ≤ - 3x - 6 +6
- 3/(- 3) ≤ - 3x/(- 3)
1 ≥ x
2d part
- 3x - 6 +6≤ 6 + 6
- 3x ≤ 12
- 3x/(-3) ≥ 12/(-3)
x ≥ - 4
x ≥ - 4 and x≤ 1
