Answer:
x=5
Step-by-step explanation:
F(x)=-3x+21,
f(x)=6 = -3x+21
6 = -3x+21
Subtract 21 from each side
6-21 = -3x+21-21
-15 = -3x
Divide each side by -3
-15/-3 = -3x/-3
5 = x
To get the inverse of a function interchange
the x's with the y'x and solve for y, as follows:
y=5x-7
Interchange to get:
x=5y-7
Solve for y to get:
y=(1/5)x+(7/5)
so I think it might be c
11+5=16 3x2= 6 8x1= 8 so add it together, 16 + 6 + 8 = 30.
42 + 28 + 12 + 18 = 100 total beads
probability of not drawing a yellow or a green : (12 + 18) / 100 = 30/100 reduces to 3/10 or 30%
probability of drawing a red or green : (18 + 28) / 100 = 46/100 reduces to
23/50 or 46%
Answer:
3rd and 4th options are correct that is 24 hours per day and 7 days per week.
Step-by-step explanation:
We need to find the conversion factors that can be used to find number of hours in a week.
We know that,
Number of hours in a day = 24
and
Number of days in a week = 7
So, Number of hours in 7 days = 24 × 7 = 168.
Therefore, 3rd and 4th options are correct that is 24 hours per day and 7 days per week.
