Answer:
5x+10
Step-by-step explanation:
let f(x)=(x-10)/5=y
now write 'x' in term of y
i.e, x-10=5y
i.e, x=5y+10
now replace y with x to get required inverse of f(x)
=5x+10
Uhhh that doesn’t seem possible but then again i forgot simple math lol
A,B and E
Explanation:
If it is 4 for $5 we would create a ratio and unit rate to test out all of the options
We want to know how much one costs first
4/5 = 1/$1.25
So you test out all options:
A. 1.25/1=6.25/5 this is correct
B. 1.25/1=3.75/3 this is correct
C. 1.25/1=9/6 this is NOT correct
D. 1.25/1=1.5/1 this is NOT correct
E. 1.25/1=12.5/10 this is correct
Answer:
D
Step-by-step explanation:
Square root of 4 is 2
square root of 9 is 3
so square root of 5 should be somewhere between 2 and 3 (closer to 2)
