Answer:
The inverse function is 3x+2
Step-by-step explanation:
To get the inverse function exchange x and y and then solve for y
y = (x-2)/3
Exchange x and y
x = (y-2)/3
Solve for y
Multiply by 3
3x = 3/3 *(y-2)
3x = y-2
Add 2 to each side
3x+2 = y-2+2
3x+2 =y
The inverse function is 3x+2
So, just take the number of girls and place that over the number of children in total. So, in this case, 18 / 30.
18/30=.6
This can be converted to 60%
1 g/mL ---------- 8.3454 lbs
1.09 g/mL ------ lbs
Ibs = 1.09 x 8.3454 / 1
Ibs = 9.09 / 1
= 9.09 Ibs
hope this heps!
Answer:
average = 52, 100 on fourth test
Step-by-step explanation:
average = 75 + 74 + 71 = 156 / 3 = 52
