C
Because they can both be simplified to 2/3
Answer:
D
Step-by-step explanation:
Since there are 6 numbers on a die that makes it a 1/6 chance to roll a 4. So to roll 2 4's would be double. 2/12
Answer:
Third choice
Step-by-step explanation:
They are asking us to find the inverse of y=5x. To do this you just switch x and y and then remake y the subject of the equation (solve for y.)
y=5x
x=5y (I switch x and y)
x/5=y ( I divided both sides by 5)
Then you just replace y with the f^-1(x) thing
f^-1(x)=x/5
or
f^-1(x)=1/5x
