Use the distance formula;
10=√(-2-x)²+(4-y)²
Now put the options one by one into the above equation;
you find that option b satisfies the equation which is the correct answer.
Answer:
f-¹(x) =(1-5x) /3x.
Step-by-step explanation:
f(x)=1/(3x+5)
Let y=1/(3x+5)
Exchanging x and y,
x=1/(3y+5)
3y+1=1/x
3y=1/x-5
3y=(1-5x) /x
y=(1-5x)/3x
f-¹(x) =(1-5x) /3x.
The expression would be (12-9)x2=6 so he had 6 comic books
Answer:
D) all real numbers
Step-by-step explanation:
The domain is the input values, in this case the x values
What x values can we use
x goes from - infinity to plus infinity, so it is all real numbers
