Answer:
see explanation
Step-by-step explanation:
to evaluate f(g(x)) substitute x = g(x) into f(x), that is
f(g(x)) = f(x - 1) = 3(x - 1) = 3x - 3
Similarly to evaluate g(f(x)) substitute x = f(x) into g(x)
g(f(x)) = g(3x) = 3x - 1
Answer:
y=
x-4
Step-by-step explanation:
3x-2y=7
-3x -3x
-2y=-3x+7
/-2 /-2
y=
x-
perpendicular lines always have opposite reciprocal slopes
3/2--> -2/3
y=-2/3x+b
-2=-2/3(-3)+b
-2=2+b
-2 -2
b=-4
y=-2/3x-4
I would say 53 minutes yup
Answer:
55/100
Step-by-step explanation:
Answer:
the proportion is 0.2779, that is a 27.79%
Step-by-step explanation:
The article reported that 1880 children ate fast food from a sample of 6765 children. We can use the rule of three to find the proportion of children that ate fast food
- from 6765 we have 1880 children that ate fast food
- from 100 children we have
children that ate fast food
that gives us that a 27.79% of the children ate fast food on a typical day. We can obtain the proportion by dividing the percentage by 100, that gives us a proportion of 27.79/100 = 0.2779.
I hope this helped you!
