Answer:
30% of her writing utensils are pencils.
Step-by-step explanation:
We can get this by dividing the number of pencils by the total number of utensils.
6/20 = .3 = 30%
The son's age is 31 and the father's age is 61.
2s-3=f
f-s=30
f=61
s=31
You just need to try with all of the pair f.ex
0,-2 -> put 0 in the x-> y=8*0-2=-2 so ok it is q possible pair of the function..
You try every pair till you find set where all the pairs fit
So set 1
1 and 6: 8*1-2=6 ok
2 and 14 : 8*2-2=14 ok
Hope I could help
Answer:
To find the inverse, interchange the variables and solve for y
f^−1(x)=−7x+7
